A new job posting at Gamasutra indicates that 2K Boston has PlayStation 3 on the brain.
However, it's quite unlikely that the PS3 project will be a port of their hit BioShock, since Microsoft paid handsomely to makes sure that particular title would be an Xbox 360 exclusive. For now, at least.
"We have had an extraordinary year with the recent release and subsequent international success of Bioshock. In light of this recent success and the pre production of our next project, we are seeking the talents of an experienced Senior Console Programmer," reads the post.
