Irrational Games and 2K Games and have been dreadfully Silent about the PS Vita BioShock project announced on stage at E3 back in 2011, leading many to believe that the project was simply silently scrapped into vaporware. Turns out that's not the case, as specified by Irrational's Creative Director Ken Levine himself over Twitter:

While details are scarce, that at least confirms that the project is still alive and the parties are trying to make it happen.

Irrational has also been rather silent recently about the announced Mac OS X port of BioShock: Infinite, but luckily that's still coming as well:

BioShock for everyone! At least we can hope so. Will Levine manage to "make a match" and to help Sony Computer Entertainment and 2K Games see eye to eye about the PS Vita project?
