Spider Man was recently launched on steam which was a huge hit. A lot of people went ahead and downloaded that game. The game had some hints in its files with references that suggest that maybe there would be a new PlayStation Launcher coming for PC in the future.
If that does happen then that would be good news for PC players and also PSN players as the Launched could later be linked to the PSN account of a user too. So PC players could gather some PSN trophies while they are playing Sony exclusive games on PC as well.
