Project Natal isn't a new video game system and so will cost in excess of 400$ like the wii. However it is completely new technology and even more advanced then the Wii so it will probably will cost around 500$.It'll be a stand alone package that comes with only the natal and their will be a xbox 360 bundle that comes with natal and a new xbox 360.
