Its a cool tech alright.

but I see it being used as a replacement for a remote control for controlling menu's etc. and partially used in game to read body language, leaning etc. but seriously can you guys imagine playing a whole gaming with nothing but the body motion control? seriously? boxing game anyone if you play for 4 hours? no way. you will still need the regular controller

and if you do go all out and use your whole body motion to play for hours, kudo's cus you'll prolly lose alot of weight.
