While I am glad that the last thirty years of innovation has led to the inclusion of a power button on the controller (why was this hard?) I'm having a hard time getting excited about controlling games with a TV remote and analog spleen. Only one analog controller? The GameCube controller was such a great design, too. What the hell, Nintendo?
The GameSpot article on the controller is here.
Edit: Apparently the controller also has some sort of spatial awareness thing going on, so you can control the game by moving and tilting and rotating the controller in space, too. Sounds like we get to rediscover gorilla arm.
