If the game is a year away from release then surely the PC spec they can rely on as the minimum will be higher and that minimum level may indeed be equal to ps4/xbone etc graphically.

Neither the PS4 or xbone really pushed the envelope this generation unlike the previous generation. I'm sure the ps4 and xbone versions will be fully optimised but PC specs move on.

Also any PC game with high cpu requirements clearly will have to be compromised for ps4/xbone. They just aren't competitive with normal PC's with regard CPU performance.
