well it was released last year in Japan and Others, but Endless ocean may end up selling 750k-1 million, most people were predicting that 250k would be a success with that game.
Also, Alone in the Dark has all of the makings of a sleeper if it can deliver in the gameplay area. If it sell 1 million across all platform I would call it a sleeper hit.
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
