Yeah, I'm looking forward to learning more about how it works. It'll probably be pretty awesome for shooters. Not sure about sports games though. It's definitely innovative and different. I doubt it'll attract people away from PS3 and Xbox 360 though.
A PR guy from Nintendo recently said that he would be "very dissapointed if there wern't playable Revolution games at E3 2006". So I would expect the Rev to be out maybe early 2007? Wait, maybe even earlier than that, as the cube isn't offering much these days... this one is hard to judge : S
