It should be noted that there's nothing in the article to indicate that Rattner has any insider info on Nintendo's plans -- more than likely he was just theorizing about what he'd like to see in a future system. Still, the idea of a camera-based 3D motion-sensing setup has incredible potential for gaming. More than the simple video transposition of the Xbox Live Vision Camera or the PlayStation Eye, a multi-camera system could model your three-dimensional movements in real time, in effect placing a digital version of you in the game. The result could revolutionize the way we play games and even how they're made -- after all, why should developers use motion captured performances when the players can provide them for themselves?
Such a theoretical system would take quite a bit of processing power, though, which might explain why Intel is talking it up -- after all, they already have a chip that can perform one trillion calculations a second. The future's so bright, we're using our Wii remotes as makeshift shades.
