As posted by GamesIndustry.biz, some technical data found on Play.com seems to suggest that the upcoming Xbox Kinect from Microsoft will appear to only support up to two players simultaneously.
While the data may not be final, it is the most information released yet and involves the Kinect camera’s skeletal tracking system. Apparently, the system will only be able to track 20 joints per active player and map them to an on-screen avatar.
Of course, this is all still speculation based on rough technical data. We will just have to wait to hear it from Microsoft to officially confirm just how many people may play Kinect at one given time.
