What i think the Wiimote has over the PS Move (if it end up more precise)

[Monteblanco]

I believe the Wii Remote's IR pointer to be more precise for shooters than the PS Move. You can tilt the Wii Remote and it will perceive the change by checking the angle of the two IR sources in the Wii remote's camera. If you tilt the PS Move, the shinning ball will barely move in the camera eye. Thus, the PS Move will need larger movements to register you aim.
