I guess Sony (NYSE: SNE) likes to concentrate on things that have worked. The company recently announced a price cut for its PlayStation 2 system. The old price: $129.99. The new price: $99.99. Yes, the wonderful $99.99 level. It's a number that draws the attention of consumers and practically dares them not to be interested.

You can bet that a lot of casual gamers will be looking to buy the console now. I know what you're thinking: Who the heck doesn't already own a PlayStation 2 by this point? Well, I'm sure there are quite a few people out there who don't have one installed in their living room.

Plus, you have to remember that there will be many parents out there who might want to pick up one of the consoles for their younger kids. Little ones who may just be starting their video-gaming lives. Why waste several hundred dollars on next-generation technology when old-generation technology will suffice for such a demographic?

Perhaps each household in Dubai will end up with its own PlayStation 3 console. The country's investment arm, Dubai International Capital, says that is has bought a "substantial" piece of Sony (NYSE: SNE), according to The Wall Street Journal. Cash-rich funds from several Arab countries have started investing in companies in the US and Europe.

The move makes a great deal of sense. Sony trades at about $49, down from a 52-week high of almost $60. Its LCD business did well in the last quarter and should show strong holiday results. The company's studio business has been solid.

That only leaves the Sony's game console business. The old PS2 video game platform still sells well, and there is some early evidence that the newer PS3 is selling better since Sony lowered its price. Nintendo's Wii has been outselling the PS3 in almost every market around the world.

Sony is not likely to be the last investment by Dubai. With the stock markets running down, there are plenty of promising companies with stock available at attractive prices. If someone has a lot of cash.
