I don't have any interest in PSN per se, but I think a PSN port is pretty far into the future - and it's not just because anything that smacks of a PSN release seems to be rumors. My own research has come up with the same, except for the last.
Just a short FYI, the only places it's currently available are Steam, Oculus and Xbox Live (XboxOne), with 'plans' of an unknown date in the future for PSN (Playstation 4)
