Another little tidbit found is that the PC version of BioShock mentions the PS3 in the PC demo code. Currently the game is only confirmed for the PC and Xbox 360, which we're sure sits very well for Microsoft given the buzz and acclaim. We also know that Microsoft isn't afraid to buy exclusive content, specifically with Take-Two. So even if this is leftover code for a PS3 version, that project may have been unceremoniously squashed many fathoms ago -- but there is no way to know at this point if this code is leftover by 2K Boston or Epic in their Unreal Engine 3. Take-Two will not even comment on this issue, and it's a special kind of no comment too. They won't comment to the point where there's not even an official "no comment" to the question of what this coding means.
