Play.com has posted a set of technical specifications for Microsoft's upcoming motion-control peripheral, Kinect. Interestingly, it says only two "active" players can be tracked at any one time.

While the camera can track "up to six people", it can only handle two "active players" at a time, relegating the rest to support roles at best, and idle spectators at worst. Asking for six players at once may have been a pipe dream, but with the Wii supporting four players, a limit of two "active players" will be a let-down to owners upgrading and expecting the whole family to be able to play at once.
