Nintendo Reveals Early Details About Revolution 

Nintendo, the world leader in video game innovation, stated loud and clear that they are not to be overlooked in the next generation home console race with the revelation of several unique features of the company's next console system, code name Revolution, to key media outlets. According to the early information, Revolution will combine powerful technology and gaming-focused features in Nintendo's smallest home game console yet. 

In its final form, Revolution will be about the thickness of three standard DVD cases and only slightly longer. The versatile Revolution will play either horizontally or vertically, allowing the user total flexibility in setting up a gaming session wherever they have a television. 

Thanks to Nintendo's hardware development partners IBM and ATI, the small system will be packed with power that will enable it to wow players with its graphics. Nintendo's legions of loyal fans will be happy to learn that Revolution will be backward compatible, playing both Nintendo GameCube 8cm disks along with its own 12cm optical disks in the same self-loading media drive. 

In the next generation, the addition of the Internet will be important to all consoles and particularly important to Nintendo. Revolution will be wireless Internet ready out of the box. 

There's much more to Revolution that will be revealed over the coming months, but the combination of its compact size, wireless Internet, backward compatibility, quick start-up time and quiet, low-power operation add up to the start of a great game system. Get ready for the Nintendo Revolution in 2006!
