Bioshock Infinite - No Lead Platform

Chris Kline posted at the Irrational Games Forums that they are doing simultaneous in-house development on the PS3, 360 and PC versions of the game. This was mostly to assuage PS3 owners' fears that it'll be a simple port:

We’re doing simultaneous in-house development on the PS3, 360, and PC versions of the game,” wrote Kline. “We all know that the PS3 is powerful but unique console with its own strengths and challenges. But compared to the PC, the Xbox 360 is challenging too. So instead of declaring a 'lead platform' and porting the game to the others, we’ve instead changed the game engine so that all platforms look (to a programmer) more like a PS3.
