I would imagine that most of the real magic will lie in making it work, and work well, as an input method - the video makes it look painfully awkward to use. Even Kinect which works relatively precisely is extremely annoying for anything else than kicking balls around on a screen. Even without interruptions like your children walking in front of the TV, getting Kinect to register an interaction correctly is a process of carefully performing some strange gesture like a wizard executing a spell while on LSD, and then doing it 5 more times until Kinect deems it precise enough. Personally I don't imagine this becoming more precise in the near future than to be useful for perhaps turning pages on a reader or tablet.
