While it wasn’t mentioned in Sony’s official announcement, developers of certain games later confirmed that PS5 exclusives like “
Horizon: Forbidden West” and “Spider-Man: Miles Morales” aren’t exclusive at all.
“No one should be disappointed,” Ryan said. “The PS5 versions of those games are built from the ground up to take advantage of the PS5 feature set, and we have an
upgrade path for PS4 users to get the PS5 versions for free. It’s about people having choice. I’m really quite pleased about the situation.”
