Even if Sony were to backtrack for this title, the restrictive reach of Sony's PSN (officially at least) and Valve's worldwide presence was inevitably going to become an issue in the long term, it is just coming to a point now in a very public way. If Valve isn't willing to go along with Sony unofficially saying to just make accounts in other regions (something that could theoritically induce liability for Valve in some of the counties PSN isn't covered in for selling a game unsupported in said countries), Sony probably has to either expand the reach of the PSN, drop the PSN requirements as part of their future PC plans, or accept the restricted reach they'll have with their online Steam releases.
