I find this highly dubious. It's not unbelievable that Kinect would eventually be available for PC gaming, but it seems Microsoft would have a higher-profile launch than this.
Apparently this man has not witnessed Microsofts PC "support" of the last decade or so.
Whether Kinect for PC gaming would even be a good idea is another question. I have a ton of room in front of my TV and Xbox, but my PC is in a small office. This isn't, I imagine, an unusual set-up.
Bingo. Games better be geared towards facial recognition, voice activation, and maybe small hand motions. No one is going to jump around in an 8x6 foot area in front of their PCs.
