Windows Phone 7's compatibility with Xbox Live could be used with Kinect, at least according to this demo from Microsoft. They recently showed off this technology demo at Steve Ballmer's MWC keynote. The demo shows the game Rally Ball being played co-op by two people; one in front of their TV playing with the Kinect and the other on the couch playing on the Windows Phone 7. This is supposed to be simply a demo to show off what the technology is capable of. I don't buy that for one second, though! How long do you think it will take for Microsoft to officially announce this?
