It's only been a few months, but already the Kinect for Windows SDK beta is moving from stage uno to stage dos. (That's one and two, vaqueros.) Microsoft's outing it in commemoration of the Kinect's one-year anniversary, and it's also launching a Kinect for Windows site and blog, too. We're told that the Kinect for Windows commercial program is still on track for an early 2012 launch, and to date, some 200 companies have agreed to take part in the pilot program. Ask for the beta 2 piece, the refreshed build includes "faster skeletal tracking, a better accuracy rate when it comes to skeletal tracking and joint recognition, and the ability to plug and unplug your Kinect without losing work / productivity." Hit the source links to get your download on, but be warned -- we've seen it off and on throughout the day.
Update: Just in case you need even more info on the movement, the official KinectforWindows.org website is now live too.
