Considering the look of the new media released so far, and the fact that you can almost run DS2 PC at 60 FPS on a toaster, I'd certainly hope that it's 60 FPS on the consoles.They didn't remaster nothing. I'm pretty sure this version was planned since the beginning, also I doubt next gen version will have 60 fps support. I mean, they are aiming to 30 fps for Bloodborne, and that's the main team.
(Also because that might make some subset of fans finally come around to the perspective of just how much better these games are at higher framerates)
