I agree forgot about Haze, also I would put Lair and biggest flop of 07.
Yes M&S was 07, but the reason I did not put it as biggest runaway hit was alot of it sales are in 08 (like 40%).
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
