Necessary evil, breh. Even though the PS5 is selling like crazy, the overwhelming majority of users are still on PS4, and don't want to feel completely abandoned until they get a PS5.
yet the OVERWHELMING majority of sales are on the PS5 for cross gen. gameplay, even if it starts on PS5 first, will have boundaries for the PS4
Best they can do is have the PS5 version run everything better, while the PS4 version's scenes are severely diminished in terms of scope, what's going on, etc.
We saw some of this w/ Horizon 2 where some parts looked like they could not run on PS4 (and probably can't)
I hope
