Two members of the BioShock Infinite team have left developer Irrational Games, reports Gamasutra, where they say Tim Gerritsen, director of product development, and art director Nate Wells have both announced their departures. Ken Levine follows this with a tweet saying: "Scott Sinclair, art director of Bio1, back in the art director's chair for Infinite to bring it home. Can't wait to show you what's cooking." In reporting this, Kotaku notes: "Kotaku has heard that development on BioShock Infinite has hit choppy waters," though they don't clarify what that means.
