This is a great idea a bit copy of wii but i wonder how it will change the gaming universe, I love playing with a controller because of it's ability of improving your hand eye coordination and it's convince. but kinect isn't ideal for people with crammed in spaces and possibly twin brothers that log into each others account.
I think this is probably the most amazing gaming leap for mankind since the Atari you control the game with full body movements not just flinging a remote around but full body movements its got great potential for exercise games and imagine a Halo or Zelda type game on that system it would be SO epic
