Sony wand it's not necessary a pointer control which is the whole point of the ball at the end of the wand. It tracks without having to aim at the camera or a IR bar. So Sony isn't just copying the Wii but trying to improve hand tracking. Nintendo control has a separate camera for each controller and one tracking bar but just like trying to record on a camcorder it hard to keep a camera steady . Now Sony's wand is the exact opposite, like TrackIR, uses only one stationary camera yet, unlike TrackIR, can track more than one person at a time. Instead of tracking IR light it tracks different colors.
So Sony wand tracking is more like TrackIR (as a mouse sub) with motion controls than the Wii-mote.
