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.
