Interesting, i was just playing this game (C1 version) last week and talking to some other dev at an indie meet up about this game. Good to know that its still in development - and on the PS4!!!
So its pretty much the route for any C2 developers looking to get their games on consoles. They'll either have to get it ported over by either another company or do it themselves by using a whole new engine that can exports to consoles. I doubt Konjak did it himself as he stated many on his blogs that he's not a developer by trade but an artist (which is what drove him to using MMF and Construct). A while back he was in talks with Nicalis for porting Iconoclast to the Wii but that never fell through, so i'm sure he's doing the same with the Bitfrostent folks for the PS4 now.
