Nah. We don't know at what cost.
We don't know if it's actual, complete parity or its just resolution and target framerate.
If both versions are indeed identical, one could imagine ps4's was somehow capped.
But like I said, I doubt they'll be the same except when it comes to numbers that are easily compared.
Now though, Destiny. That was exactly the same game. Magically o not, Bungie did just reach parity, but I don't see people getting mad at that for not having better AA and whatnot on PS4, although it is safe to assume it could look/perform much better than it does.
