The last guardian is a PS3 game. I really hope a PS4 port (even remastered) would run at 60fps and not at 30fps with frame pacing issues like Bloodborne.
So they really should borrow TLOU Remastered 60fps engine or at least use the techniques Naughty dog did to (successively) port the PS3 30fps game to 60fps on PS4 as explained here:
