PS3's are not completely sold out WW. Nintendo sellin damn near 4m in one month and then selling half a million the next is an obvious demand problem.
I'm sorry PS3 is just not in as much demand as the Wii is.
Bet between Slimbeast and Arius Dion about Wii sales 2009:
If the Wii sells less than 20 million in 2009 (as defined by VGC sales between week ending 3d Jan 2009 to week ending 4th Jan 2010) Slimebeast wins and get to control Arius Dion's sig for 1 month.
If the Wii sells more than 20 million in 2009 (as defined above) Arius Dion wins and gets to control Slimebeast's sig for 1 month.
