I called this my game of the show at TGS back in September of 2010, so as you can imagine I've been dying to get my hands on Child of Eden. In Japan we still don't have a launch date, so like REZ before it I had to import it. In the video show shown the Kinect is used through-out, you can use the controller but using Kinect just gives the player an experience that they've never felt, a feeling of conducting an orchestra.
Enjoy the videos.
Update: 2 new videos added, Matrix, Evolution.
