"My guess is that where this ends up is: motion controllers end up with half the market. And the other half still ends up with a more traditional game controller."

Traditional controllers won't become extinct, he said. "I really don't know if you're going to want to play FIFA with a motion control device. First off, a 75-minute session would be frigging tiring, jumping all over the place. And frankly the traditional controller is pretty fun. I don't know where, for example, shooters end up, but the camera and/or infra-red reception doesn't give you the precision for a shooter that you get out of a traditional controller. While you can certainly look at Natal and say, yes I can have a gun and do this with it, I don't know that that's necessarily how I want to play."
