While
BioShock 2 was announced to have been pushed back to 2010, that
isn't the only title to do so.
Mafia 2 ,
Max Payne 3, and
Red Dead Redemption are all going to be 2010 releases. At E3,
Mafia 2 was
said to be 2010 so that's not a surprise.
Red Dead Redemption I think had a window of Q4 which spans 2009 to 2010.
Max Payne 3 had a Winter 2009 set up but that is now no more. Poor 2K Games. But, look out for next year when all these titles hit for them.
