Electronic Arts (NASDAQ: ERTS) hasn't been doing as well as its colleague Activision Blizzard (NASDAQ: ATVI). Indeed, when it comes to the numbers, Activision, which is responsible for franchise hits Guitar Hero and Call of Duty, has its competitor beat.

But EA recently released an exercise system for the Nintendo (OTC: NTDOY) Wii that was highlighted at CNBC.com. The piece mentions the enormous marketing presence that is supporting EA Sports Active. You get a couple accessories with the software: a leg strap that is used like a controller to interact with the screen, and a resistance band to increase the effectiveness of the workout. Oprah Winfrey's trainer apparently assisted EA with the design.

One of the things I have long coveted (other than my new obsession, the House of Pain Adidas) is a Nintendo Wii. You see, I am a bit behind on the gaming world, but I like the Wii because I could play golf with Tiger Woods and my (bad) swing. Perhaps I may be able to get a Wii for less than the shoes now, as long as I am not in the U.K..

Okay, video-game sales stats are out for the month of January. Please tell me there are some exciting changes in the ranking in terms of which gaming console dominated the charts in the U.S. Please tell me that it wasn't the Nintendo (OTC: NTDOY) Wii -- that would be too boring. Please . . .

Ah, forget about it! There's no suspense to this. We all know that the Wii is number-one yet again. In January, the console moved just under 680,000 units through retail shelves. Microsoft (NASDAQ: MSFT) sold over 300,000 Xbox 360 systems, and Sony (NYSE: SNE), once again, came in third place, convincing a little more than 200,000 gamers to take a chance on its more expensive hardware. Believe it or not, it isn't just price that is sending people to the Wii. If it were just price, then the Xbox 360 without the hard drive would be in first place. No, the Wii is turning into one huge entertainment icon.

Okay, so less than two weeks ago, I penned a piece about the video-game wars. Sony (NYSE: SNE), Microsoft (NASDAQ: MSFT), and Nintendo (OTC: NTDOY) are battling it out in the marketplace with their respective consoles. I proffered that perhaps Nintendo might be making too many Wii systems because, at the time of the piece, I noticed that, in my area, stores had plenty of Wii's (and plenty of Wii Fit units, too). If you wanted a Nintendo system, you got it. Well, let me give you an update on how the Wii's are faring where I am, as well as some sales data from November.

I have to say, I turned out to be wrong. And I have to say that those who left comments on my Wii article turned out to be correct. They took me to task for suggesting that the Wii needed to be limited. Indeed, another check of the Wii supply showed that all the stores around me sold out of their inventories. And now, I've been hearing that everyone is desperate yet again to score the console! In fact, here's an interesting thing not about the Wii, but about the Wii Fit. There was one store that had a huge number of them, boxes piled high. They were gone in something like a few days flat, quite unexpectedly. Now, as I cautioned in my previous piece, please don't take this one account as any sort of scientific conclusion about Nintendo's prospects. Nevertheless, I'm amazed at how fast things have changed in such a short period of time.

And now, let's look at some sales figures for the month of November. Once again, Sony's PlayStation 3 and Microsoft's Xbox 360 couldn't come close to the Wii. The Xbox 360 moved more than 830,00 units, while the PlayStation 3 sold over 370,000 systems. Nintendo's sales? Try more than 2 million. Casual gaming truly is king. I don't think there's any doubt that the Wii will dominate in December. And in terms of Sony and Microsoft, I think the latter will wind up in second place. These are predictions that are pretty obvious. No need to go out on any limb.

I happened to be reading two articles on CIO.com yesterday concerning Nintendo (OTC: NTDOY) and its Wii distribution strategy. There was an older one from August discussing the reasons why the Wii has been in short supply. Was Nintendo purposely making the Wii a rare commodity? Were there indeed production problems? The second mentioned Nintendo's decision to increase the availability of the Wii so that as many consumers as possible will become part of that system's user base. The headline said that Wii shipments will be doubled.

Let me give you my unscientific perspective on this topic. On an anecdotal basis, over the weekend, I noticed that, in my area at least, if you wanted a Wii you got a Wii. Also, if you wanted a Wii Fit, you got a Wii Fit. You didn't have to wait in line at three in the morning, you didn't have to go online, punch up eBay and get into some obnoxious bidding war to score a console so that your kid would be content on Christmas morning. The availability of the Wii hasn't been better.

And I tell you, this could be, from one point of view, bad for Nintendo. It might even be good for Sony (NYSE: SNE) and Microsoft (NASDAQ: MSFT). After all, if the Wii demand is possibly now satiated (according to my anecdotal observations), then interest may jump in the PlayStation 3 and Xbox 360.

The month of October was good to the Nintendo (OTC BB: NTDOY) Wii console. Actually, every month seems to be good to the Wii console. According to the latest sales figures, the Wii sold over 800,000 units during the Halloween season. Nothing scary about that.

Of course, Sony (NYSE: SNE) probably was a little spooked. The company's PlayStation 3 system came in a distant third to the Wii. Microsoft (NASDAQ: MSFT) probably felt all right. The Xbox 360 came in second place, fueled by a recent price cut. Believe it or not, you can actually get a video game system for less money than it costs to acquire a Wii. The Xbox 360 version without a hard drive goes for $199. Still, people are willing to pay a premium for casual gaming.

After I got through checking out the hardware sales, I wanted to see how software had performed last month over at Gamespot. I have to admit, I was pretty shocked to learn of the "conspicuously absent" Guitar Hero World Tour game. That bugged me because one of the prime reasons I own shares of Activision Blizzard (NASDAQ: ATVI) is the Guitar Hero franchise. However, one thing to keep in mind is that the title still has time to chart. It was released the last week of October, so perhaps the November rankings will be kind to it. Also, the new Call of Duty war adventure hit the street this week. Anecdotally, I know there's a lot of interest in that game.

No, you're not surprised. Nintendo (OTC: NTDOY) moved the most video-game consoles in the U.S. in July. According to this Bloomberg article, which cites monthly data supplied by market-research firm NPD, gamers purchased over 550,000 Wii systems. Sony's (NYSE: SNE) PlayStation 3 was snapped up by almost 225,000 players, and Microsoft's (NASDAQ: MSFT) Xbox 360 sold about 205,000 units.

There's no question about it now -- the Wii should dominate the holiday season. Momentum is behind the company's strategy of creating products that appeal to casual gamers. I'd be shocked if the fad all of a sudden burned itself out, although Douglas McIntyre did write recently about the possibility of Nintendo running out of steam at some point. The Wii Fit exercise system was the second best-selling software title in July. That property is definitely helping drive Nintendo's fortunes.

In other software statistics, Electronic Arts (NASDAQ: ERTS) was number one with NCAA Football '09. Activision Blizzard (NASDAQ: ATVI) came in third with its version of Guitar Hero for the Nintendo DS handheld unit. EA should come out on top again next month since the new iteration of its Madden franchise came out earlier this week. There was a lot of excitement over that game, as there traditionally is every summer.

Well, another month's gone by, and I see that the Nintendo (OTC: NTDOY) Wii system is still the number-one selling console in the United States. Guess I shouldn't be surprised. According to Bloomberg, the Wii moved over 666,000 units in June. Yeah, that may be an evil number, but it's a righteous one to Nintendo, since Sony (NYSE: SNE) sold a little over 400,000 PlayStation 3 consoles last month while Microsoft (NASDAQ: MSFT) convinced just under 220,000 users to adopt the Xbox 360. So if you add the performance of the PlayStation 3 and the Xbox 360 together, it's still less than Nintendo's.

Bloomberg reported that the Wii has been purchased by (or for) 10.9 million gamers, making it the number-one installed platform out there. Driving the results in June was the Wii Fit, which continues to be popular and difficult to get. However, the top-selling game software was not Wii-related, it was PlayStation 3-related, believe it or not. Metal Gear Solid: Guns of the Patriots, distributed by Konami (NYSE: KNM), sold over 770,000 discs. One big opportunity Nintendo needs to work on is third-party attachment rates. As several readers have mentioned to me, the attachment rates for the Wii isn't as good as it probably should be. Most Wii owners are in love with Nintendo-published games, but sometimes don't see the value of software made by other publishers. An increased focus on this would be helpful to the platform and its continued success.

Nintendo is setting itself up very nicely for the holiday season. Sure, it's the height of summer, but it's never too early to be thinking about the holidays, is it? I would love to get into Nintendo's stock, but I am still stubbornly holding out for a better pullback on the ADR's. I'd love to see the price close below $60 at some point.

Disclosure: I don't own any company mentioned; positions can change at any time.

Take-Two Interactive's (NASDAQ: TTWO) Grand Theft Auto IV game stole the number-one position on the software sales chart for May, according to data from market research firm NPD. It sold over 1.3 million copies last month, and it has moved over 4 million since it hit the street. I figured Take-Two would be taking the top slot here, but the big question on my mind pertained to how Nintendo's (OTC: NTDOY) Wii system would do in May. After all, the fad has to wear out at some point, right? At some magical juncture, either Sony's (NYSE: SNE) PlayStation 3 or Microsoft's (NASDAQ: MSFT) Xbox 360 will displace the Wii and become the top-selling system of the month.

Well, that hasn't happened yet. The Wii sold the most, moving 675,000 systems. That was more than three times the amount of consoles sold by PlayStation 3. And as for the Xbox 360, that came in dead last, moving only 187,000 units. All told, total video-game sales, including hardware and games, increased 37% year-over-year. Yep, video games are still hot.

I'm going to predict that the Wii Fit will be the top-selling game package for the month of June. This thing is flying off the shelves in my area, even at $90 (apparently, high fuel costs aren't hurting Nintendo's clientele). Does that mean that Nintendo might make for a good short-term trade? Maybe, but I'd prefer buying it safely below $60 per share. As of this writing, it's trading well above $60 per share. I continue to hold Activision (NASDAQ: ATVI) as my play on video games, and will be keeping Electronic Arts (NASDAQ: ERTS) in the back of my mind as August approaches, since that will be when the new Madden game arrives in stores. Not sure if that's worthy of a trade yet.

Disclosure: I own Activision; positions can change at any time.

Best Buy, Inc. (NYSE: BBY), always the one to capitalize on unique marketing opportunities at every chance it gets, sees another one coming down the road very soon. The upcoming Nintendo Wii gaming title Wii Fit, which is to be released on May 17, should be one of Nintendo's hottest gaming titles of this year.

The Wii has made its mark using interactive and physical gameplay, requiring the physical involvement of the players instead of the couch potato thumb involvement of regular competitive game consoles. For that reason alone, the Wii has become immensely popular, outselling both the Sony Corp. (NYSE: SNE) Playstation 3 and the Microsoft Corp. (NASDAQ: MSFT) Xbox 360.

Best Buy's marketing angle with the Wii Fit release happening in over a month includes some teaser ads near fitness DVDs that use Nintendo's catchy Wii slogan: "how will it move you?" The new Wii Fit game, which will include a "balance board" to help those playing the game to interact as much as possible physically, needs to have a "best outlet" for sales here in the U.S. due to its existing mass population appeal, and if Best Buy can ramp up anticipation correctly, it may become the outlet to buy the Wii Fit game title come the third week of May. That is, unless competitor Circuit City Stores, Inc. (NYSE: CC) becomes aggressive on its Wii Fit marketing -- and I don't see that happening.

Whoever invented the Wii Fit, a virtual gym that can be used in conjunction with the gaming console, deserves a medal. Heck, he or she deserves a raise because it's going to be a huge seller for Nintendo Co. (OTC: NTDOY).

This game is perfect for someone like me who doesn't exercise as much as he should, which in my case means hardly ever. The Wii Fit, which will be available May 19, also will be useful for parents trying to get their children to exercise more. "Wii Fit is all about breaking the definition of video-gaming, about something that keeps you and your family fit and engaged," said Reggie Fils-Aime, president of Nintendo's U.S. division, in an interview with The Wall Street Journal.

Nintendo officially launched a game in the US which has a feature that Sony (NYSE: SNE) and Microsoft (NASDAQ: MSFT) have yet to introduce. The Nintendo Wii Fit is aimed at gamers who want a little exercise. The new product may speak volumes about why the Japanese company has a sales lead over its two rivals.

According to The Wall Street Journal, the new product "comes with a weight-and-motion sensing device called the Wii Balance Board." Nintendo is also launching a service that allows video games to be distributed over the internet.

The Wii Fit will be introduced with games including one that gives the sensation of skiing.

While products like the Xbox 360 and Playstation 3 are based largely on the old model of a console that the user operates from a fairly fixed position, Nintendo has moved in the direction of gaming that involves the user participating directly in the action on the screen. The Wii Fit has sold 1.4 million units in Japan in a little over two months.

Now Microsoft and Sony have something else to worry about from the market leader.

Nintendo's stock was up again last night in Tokyo. No wonder. It is still beating Microsoft (NASDAQ: MSFT) and Sony (NYSE: SNE) with newer and better innovations in the game console business.

The latest gem from the Japanese gaming firm is the Wii Fit.

According to Reuters "the new game features a pressure-sensing mat called the "Wii Balance Board", which looks like a set of bathroom scales and can sense when a person moves and leans, enabling players to "head" virtual soccer balls and experience ski jumping on a TV screen." It can also be used for yoga and other exercises.

The poor people who make the Xbox 360 and PS3 must be scratching their heads. First, Nintendo beat them in units sales for next generation game sales. Now, the smaller company comes to market with a product that pushes the envelop of what a video game is and what it can do.

Perhaps the people at Microsoft and Sony are not interested in fitness.
