The cope is strong.
Anyway, 800-ish GB on the Series X is still mostly tolerable, with games hovering around 100gb. 8 games or, so. It's still messier than I'd have liked, though, once you start factoring in one or two larger games. COD:MW eating up something like 200gb of your drive, leaves you just 6 games. That's not a lot. 600-ish GB on the PS5 is getting very close to crossing into "actually not good" territory. 6 games, or so. However, one big game really hurts. COD:MW eating up 200gb leaves you just four games. That's not going to be enough for some folk - especially if you're interested in trying out a bunch of new games at launch.
The saving grace here is that we were told that a huge amount of space is actually due to asset duplication to deal with platter spinning on older HDDs. With SSDs as standard, this type of duplication shouldn't be necessary, if I've understood this correctly. Hopefully this means 100gb games aren't the standard this generation.
