Nope.
Main selling price for the Wii was the motion sensing Wiimote novelty, and the games that went with it. The Wii is still a much cheaper(at $200) than the top selling 360 SKU right now(the 250 GB 360 “S” at $300), and that hasn't stopped the 360 from outselling the Wii for 4 straight months has it? The point is, the PS3 Move now does everything the Wiimote does and does it better, and it's in magnificient HD as well. So even at $300 for the PS3, the PS3 still outsold the Wii for September with the release of the PS3 Move. Microsoft's Kinect is experiencing excellent pre-order sales as of right now. I am gonna be expectoing the 360 to easily outsell the Wii for this comming holidays with the Kinect launch. Kinect already sold out at Gamestop in the US.

Yet about the same price as the base 360, which still gives you much more power and video quality than the Wii.
