This video just popped up on YouTube, purporting to be the debut advertisement for Kinect once its television marketing campaign begins. Ads that leaked out before this one were "unfinished."

It's certainly professionally edited, and contains some footage we haven't seen in the previous three rough cuts. It still keeps the visual focus on the people playing the games while only throwing in a few seconds of on-screen gameplay at the end. Music seems about right for a Microsoft advertisement, too.

We've contacted representatives of Microsoft for comment on this; we'll update here if they reply.
