Sony have already said they like the model GoT used. I expect a 4k 60fps patch for TLOUII to drop soon, along with the factions update. Which will be a free update, to encourage sales. Stand alone Factions may come at a later date. Naughty Dog want to move on to their next big project which is already in full development, they dont have the resources, nor the will, to Remaster a 2020 game. GoT looks amazing on PS5 at 60fps, I dont expect much more, other than updates to Legends mode.
