Anyone who has anything other than the Wii at first place is fooling themselves.
At any rate, my predictions...
Wii: 110 Million
PS3: 40 Million
360: 35 Million
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
