Chris Klime, technical director at Irrational Games has confirmed that all versions including PS3 will be developed in-house and not by any other studio:
We’re serious about making sure the PS3 version is great, and here’s a little info on how we’re going about doing it.
To answer your question, we have no plans to hand off the PS3 version of BioShock Infinite to another studio. In fact, it’s not a “port” at all. We have a much larger team than we did on the original BioShock, so we’re doing simultaneous in-house development on the PS3, 360, and PC versions of the game.
