I'm less interested in the gaming part but more in the ways this will invade our daily lives. If it works as advertised then it might soon be built into TV sets, PC monitors and all sorts of public infrastructure that we can't even imagine, yet. If microsoft can hold a big piece of that cake then that should be huge. I mean, obsoleting TV remote controls alone is big, but only the tip of the iceberg. How about interactive advertising (stand in front of a shop-window, interacting with a bigscreen), touch-free car dashboard, the whole "home automation" area, and so on. This is ofcourse all under the assumption that it really works as well as shown in those videos.
