Do'nt think so, man
GZ on PC is one of the best ports I've ever seen. It's ****ing well optimized with better textures, shadows, lighting effects than PS4 and 2K-4K Resolution support in addition
I don't understand Why you give for granted that PC version has been developed by a different developer/team ? or that it will happen as with BAK?

GZ ended up being a good port, but you have to take into consideration that it's a very small demo compared to TPP. That's not to say that TPP will not end up being good, too, but personally I don't want to risk it on PC, since "Konami" only started developing it in July. To me, that just sounds like a rushed job, especially considering that GZ's PC release was nearly a year after it was released on the consoles.
Besides that, MGS just doesn't feel right on a PC. If there's any sort of exclusive functionality with the DS4 controller on PS4, you might be missing out on some things.
