Ken Levine has in recent months repeatedly talked about the possible Bioshock game for PS Vita, and pointed out that the concept works for some time, but its release is still in the distant future.
Judging by the messages that Levine announced on his Twitter profile realization Bioshock Vita depends solely on the agreement honcho from 2K Games / Take-Twoa and Sony, which have not yet been able to find a common language.
We hope that deal would be reached within a reasonable period so that on their portable consoles enjoy Bioshock.
