BioShock 2 in Development

According to Next Generation, the latest financials of Take-Two as well as their PR confirm that BioShock 2 is in development.
Take-Two subsidiary 2K said that the sequel to 2007's hit title Bioshock, developed by 2K Boston and 2K Australia, will be arriving in fourth quarter 2009. The first Bioshock has sold 2 million units to date.

As development of the title has moved to 2K Marin from 2K Boston/Australia, that leaves the question about whether or not Bioshock frontman Ken Levine will be involved in the sequel's development, and what exactly 2K Boston and Australia are working on if not Bioshock 2.

Take-Two boss Strauss Zelnick said during a Tuesday earnings call, "Ken is a terrific asset in the company, and he's a brilliant game developer. ... He will be working on Bioshock 2 and he will be working on a new IP."

From the earnings call, however, it sounds like the new IP will be the primary focus of Levine and 2K Boston and Australia, with less time being spent on helping 2K Marin with development of Bioshock 2.

"A lot of the work will be done at 2K Marin, but that's not to say Ken is not involved. He's critical to Bioshock," said Zelnick.
