According to some quick investigative work by Kotaku's Jason Schreier, a "top-secret" 2K studio is working on a "top-secret" new BioShock game. Schreier found this out while reporting on a story about Hangar 13 and how that studio lost its way with Mafia III.

This should probably not come as too big of a surprise to anybody. It will be interesting to see how this new BioShock game fares without Ken Levine and Irrational Games.
