How many 360's were available at launch? That launch did not go too bad for me personally, and if this is a similar quantity, I think the higher price might make the launch go the same way...
My biggest concern is that the limited number of units will irritate the game developers into delaying games or porting them to the 360 instead (assassin's Creed not exclusive anymore I see).
Anyways, Wii is gonna be there, and will see us through the the twilight even if the PS3 is not...
