Sony makes money hand over fist. They don't care about ports. Consoles is where the money is at for them. GTA 3 :Vice City was originally released on consoles, but got a PC port as an after-thought. It was IDENTICAL to the console version. I think that was more of a one-off, though future GTA releases were released on PC.

I'm not surprised there wont be more console games released for PC. The original Metal Gear, got a PC release (and GOG release). There are exceptions.

Sony makes good products. Especially their music equipment. But as far as gaming goes, why would you be surprised that they wont release more games to GOG? They're not quite as bad as Nintendo. Nintendo will litigate you in court for simply releasing an emulator, and they'll destroy you if they can. Sony is a little better but not by much.

PC games have the hugest library in the world, dating back to the 80's at least, far surprassing consoles in whole. Screw consoles. Go PC is what I say. And leave Sony and Nintendo behind. (just my opinion)
