Hi my friends!!! please help me,wich one should i pick?:

Project Natal

No Strings (or Controllers) Attached.

A revolutionary new way to play: no controller required. See a ball? Kick it, hit it, trap it or catch it. If you know how to move your hands,you can freely moveor speak you and your friends can jump into the fun -- also more important is the Project MILO because thats what I really call revolutionary

Motion Plus

which can determine rotational motion. The information captured by the angular rate sensor can then be used to distinguish true linear motion from the accelerometer readings.This allows for the capture of more complex movements than possible with the Wii Remote alone.Cheapest by now but i'll have to buy 3 or atleast 2

PS3 motion control

Sony had a more primitive (but still impressive) tech demo where objects were manipulated and foes were slain with virtual weapons, it was quite impressive also seems fun.Based on the PlayStation Eye, light-emitting diodes, and wireless controllers with buttons could track every movement that was made.

wich one should i pick? My purchase will be based on every comment
