And how exactly would they do that? PC's don't generally have 1 set of full graphics card memory. Nor do they generally run the OS of a Playstation Station 4. Now, if you mean Playstation Now, the streaming service, sure, if you want to stream your games, I suppose that could happen, although you'll be paying monthly fees plus game fees for an inferior experience, but whatever. Even Xbox One, which is far closer to PC still requires different code running on both platforms.
