Err...Ubisoft are releasing a camera and a Wii exercise game this year that does most of what you're suggesting-
UBisoft :Your Shape

Was this demonstrated at all because looking at the video thats not exactly the same thing. Judging by the video that camera is only tracking your silhouette, it's not doing 3D motion tracking and cannot cope with occlusion to the extent Natal can. Also notice she is in a brightly lit room, with a background that is light and she is dark so that the camera can see her easily.
Natal is doing full body tracking in THREE DIMENSIONS. For example, lets say you're doing a pose with your body square to the camera and your arms held out straight in front of your chest, palms together. Based on your silhoutte that camera would not be able to tell what your arms were doing because it would be in the same 2D space as your chest. You could have your arms straight, bent at the elbows and hands up like a prayer pose and to the camera it couldn't tell the difference between that and your arms straight out. Natal can see in z-space, depth, it would be able to see where your arms are, how forward they are, even if your hands are flat against their palms or your fingers are locked together in a fist.
Do you see the difference?
