I'm wondering what the official line will be from Sony regarding buying cross gen games on PS4 and PS5? It would be nice to know that if you buy a game on PS4 you'll automatically be able to run both the PS4 and PS5 version of the game of you decide to upgrade your system?
Have Sony said anything about this topic?
Sony have said bugger all but it will be up to each publisher to decide this anyway. Some of them have already gone on record, like CDPR said you'll get the PS5 version of Cyberpunk 2077 for no cost. EA have said the same with Madden 21 and FIFA 21.
