I managed to get the ps5 a couple days after original release.
While there aren't a lot of games to play on it that are "ps5" games, there are tons of PS4 games that work on it wonderfully. Rocket league and Warzone look amazing in 4k. The controller feels great, and I went from the original ps4 to ps5. So if you have the ps4 pro, i don't know how much different it will feel for you, but moving from the original release day ps4 to the ps5 everything loads so quick, feels fluid and smooth.
