In a call to discuss its quarterly financial results, Take-Two announced a sequel for BioShock. No details regarding the game were given. However, Take-Two executives confirmed previous rumors that the Irrational Games team (now 2K Boston) would not be developing the sequel. Instead, 2K Marin has been tasked with creating the next in the BioShock franchise. 2K Boston's Ken Levine will be involved in the sequel, however.

If you're wondering why Take-Two would announce Bioshock 2 so early, it is likely due to EA's recent attempts at acquiring the company. Confirmation of a BioShock sequel will only increase Take-Two's value.

BioShock 2 is set for release in Q4 of Take-Two's fiscal year 2009. That would be around October '09.
