We knew that Microsoft’s hit motion-control accessory for the Xbox 360, Kinect, was coming to Windows eventually. They’ve been hinting at it, people have been hacking it, and they even released an SDK a little while back. But one of the last things Ballmer said tonight at his keynote was a definite date for when Kinect would be coming to Windows: February 1st.

That’s really all there is to it.

If you’re interested in contributing, check out the SDK, or if you just want to see what people have put together (there has really been some mind-blowing stuff over the last year), scroll through our Kinect tag.
