According to the magazine and proven NeoGAF proxy SuperSonic 1305, the PlayStation 3 port will pack improved visuals over the previous PC and Xbox 360 editions along with the previously-released free downloadable content.
When reached for comment today, 2K Games told Shacknews it had "no comment" on the matter. A PlayStation 3 iteration of BioShock was denied by creator Ken Levine last August, though his phrasing only indicated the studio was not pursuing a PS3 version at that time.
EGM's writeup further states that the upcoming BioShock 2 will be unveiled around September as well. No platforms have been announced for the 2K Marin-developed sequel, though PC, PlayStation 3 and Xbox 360 editions are expected.
Hah! My guess is they were thinking of doing it in the middle of development (which would explain the PS3 references in the input config), then changed their mind and focused on PC / 360, and then later decided to pursue a PS3 port.
That is, of course, if they really are doing a PS3 port. We'll find out in a few months.
They were looking at having an external studio handle the port prior to signing the exclusivity agreement with Microsoft for the 360.
i thought all u3 engine games had ps3 stuff in config
