I wonder how good that Kinect is. I heard the Kinect 1 for PC was way better than the XBO 360. So if it's the same kind of situation, then meh.
I'm pretty sure the Kinect, that comes with the Xbox One, is better than the current Kinect hardware on the PC. I seem to recall some articles, from a couple of months ago, talking about Microsoft bringing the second gen. Kinect over to the PC.
