Ken Levine, the major influence on the critically acclaimed underwater FPS that is 
BioShock, has put enough distance between it and himself as is courteously possible without actually saying, "Not with a barge poll".
He tells 
Gama, "I'm not working on 
BioShock 2. I make no claim to anything on 
BioShock 2, and I think it's important that that's their (2K Marin's) product, and their culture. Because you can't just clone a studio."
Levine not being on the project hasn't meant, however, that it's under-resourced. If anything the opposite is true, having had yet another 
development team added to it this month, despite having 
slipped into next year.
