Shadowbringers started doing more phasing-type stuff. Depending on where you are in the story your sky could be bright while someone else's is dark and I think there was a brief part before The Heroes Gauntlet where it was a star shower. So I could see them doing something in the next chunk of story where along with the spooky towers we start seeing a dozen Dalamuds dangling in the sky, while new players just see regular old ARR. With the addition of flying to older zones it's possible that they intend to use them for more than just a couple fetch quests, also there's the part of the Endwalker trailer where La Noscea is on fire. But I assume the story will have us ultimately preventing the full calamity, so who knows how far they'll take it.


If you just meant a calamity in the sense of like a 1.0 to 2.0 change in the game itself, I don't really see that happening. That story was made to explain the changes they needed to make to the game, not the other way around. There are definitely aspects of the game that need a tune up, but nothing on the scale of blowing the whole thing up and staring fresh.
