One thing I'm really curious about is the lack of cross gen multiplayer support, and any possible workarounds. We know PS4 and PS5 players won't be able to play together (and we can assume the same will be true for Xbox One and Series X).
But will there at least be a 60 fps mode on the PS4 version when playing on PS5? And
if you play for a while on PS5 and then want to switch to the PS4 version so you can play with your PS4 friends, will the same save files at least be compatible with both versions of the game? Not that I want an answer now. I agree you should always respect your NDA.
It is unfortunate, though, that such a co-op focused game is going to be one of a handful of titles that doesn't offer cross gen multiplayer. The developers have said they're interested in adding it later, but it won't be available at launch.
I'm also going to tag
@Karak on this one. I'd really be interested in hearing this topic covered in reviews.
