If you haven't seen it already, the new Kinect SDK has been released. You can download the SDK, as well as the developer toolkit that goes along with it (two separate downloads) here.

This looks like quite an update to the SDK, with even more improved skeletal tracking, plus lots of goodies bundled with the toolkit. If you are using the old SDK, its time to upgrade!

By the way, saw the following earlier about using the kinect for mocap. Should be a godsend for the indie dev community.

This shouldn't be limited to just full body tracking. You can probably also get usable facial mocap from the depth data. (Try http://www.cgal.org/)
