Scott Sinclair, the art director for the original BioShock game released in 2007, is now the art director for BioShock Infinite, studio head Ken Levine said today on Twitter.

Sinclair replaces Nate Wells, who left Irrational Games recently after spending 13 years with the company. According to a report from Gamasutra, director of product development Tim Gerritsen also left the studio.

BioShock Infinite was delayed until February of next year. Publisher 2K withheld showing the game at this past E3 and will not show it at Gamescom later this month, either. "That way, the next time you see our game, it will be essentially the product we intend to put in the box," Levine said.
