The bigger question here is, do you WANT this to be Bioshock without Levine?
Bioshock 2 was one of the best games from last gen and it had minor Levine input, if I recall correctly. For me, Bioshock is by far the most exciting game from the potential options here. It would be impossible for me to care less about another Mafia game and I'm kind of apathetic to the idea of more XCom.
