We have no idea on either at the moment, but it can be assumed that the game will atleast be ported over to PS5. No guarantee on a free upgrade - The main reason they did it for PS3 to PS4 is because the new expansions litterally would not work on PS3, ARR barely worked at 20fps on it so the larger areas that were required to make flying a necessity simply wouldnt run... or rather, they did, as i recall PS3 being dropped on stormblood, not HW, i cant remember...but yea. I doubt we'll see as big a technological gap between PS4 and PS5 as we saw between PS3 and PS4 for ff14
