A sizable delay has just been just announced for Bioshock 2. Take-Two is now saying it will be released sometime in the first half of 2010.

Personally, Max Payne 3 is the one I'm really looking forward to playing.
"The decision to shift a release date is never an easy one, especially with a product as highly anticipated as BioShock 2. We felt that it was essential to invest the additional time to ensure that this title will deliver what its fans expect and deserve. As a result, we will now be launching sequels to several of our strongest franchises - including BioShock 2, Mafia II, Max Payne 3 and Red Dead Redemption - during the next fiscal year."
