I think it will be for 2025, beyond that who knows. PS5 only has 16gb (shared).
It's important to note that just because a game will use more than (say) 12gb VRAM, doesn't mean it needs it. Similar to how upping your power limit on your GPU will see it use that budget, but not gain much more performance.
I agree though, going from a gen where AMD's cards had 16, 20 and 24, and Nvidia's upper offerings having 16 and 24, it does seem stingy to not increase that for this gen. It looks more and more like the 5000 Super series will be what everyone wanted from this release.
As always though, 3rd party benchmarks will be revealing.
