I heard Kinect takes control over your home entertainment preferences. If Kinect detects that there's more than a certain number of people in a room, it will refuse to play a movie. These kind of gestures, at best, seem bothersome to me.
I see the next Kinect sensor as more of a home entertainment assistant than something purely related to gaming. That said, Microsoft seems to be shiping out early copies to devs in an attempt to gain an edge over SONY. Smooth move, but then again, we don't know if SONY has already done the same with PS4.
