Retailers Believe the Wii Will Outsell the PS3

the only down part of the wii is that extra Wiimotes cost $39.99 and the
Nunchuka is $19.99, but games will be $50 and not $75 like ps3 games so ya.

Edit: Quote
" But while only 400,000 PS3s will be available at launch, the Times claims that the Wii will be “far more available in stores this holiday season” than its competitor due to its cheaper and simpler form factor. Nintendo has since announced plans to ship 4 million Wiis worldwide by the end of 2006, nearly double the 2 to 2.3 million shipped PS3s Sony is now forecasting."
