I cancelled my copy. I'm going to wait for the PS5 version. Heres hoping for 60fps.
Square's words on PS5 is they don't see a reason to make a game dedicated to that hardware with it being backwards compatible with PS4, it'll offer enhancements that will make the experience more enjoyable but no reason to alienate an already established player base.
Anything for the next gen consoles for both ps5 and xbox wont be until much further down the road.
