Says it's by the same person who leaked the dev kit pictures. I remember seeing a video not long ago about a TV or screen of some sort that could detect finger movement. Kinect 2 will probably be the same. With that kind of precision mastering a game could be as hard a learning an instrument, with an addictive hi scoring game that would be crazy.
Not sure if it would be better for strategy games but would make navigation a lot more fun.
