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.

In terms of production, we're constantly testing our code on the PS3, as it is part of our QA team's daily test plan. All of our programmers have PS3 and 360 dev kits on their desks, and can test on the PS3 just as easily as on the 360. To make sure we find and fix problems as quickly as possible, we have a "continuous integration automated build system" that rebuilds the PS3 version and runs basic tests on it every time a programmer or artist makes a change to the game. It even emails them right away if they break something. In addition, we've also built tools that allow artists and designers to instantly check whether or not their levels will fit in memory on all three platforms, without ever leaving the editor.

I hope that gives you some confidence that we're serious about making a great PS3 game.
