I have seen a wii or 2, but most of the time the next time i come back to the same store they are gone. I even saw 5 WiiFit in stock at Walmart... But 2 days later none.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
