I think Sony has a huge backlog of games they want to port onto PC. Once they get through those games, I think the games will be coming to PC a lot quicker. The main issue with PC right now is MS is taking their sweet ass time getting Direct Storage to be GPU accelerated. So that may be one of the issues that Playstation studios are having when attempting to port games.
