If the next expansion is basically a rehash of FF10's story with us traveling to Zanarkand and dealing with Sin then I've lost all hope for FF14's creativity team.

Referencing past games or bringing back a group of bosses for side content is fine, but they should never just reuse a previous game's storyline for the MSQ plot. Post-Endwalker and the second half of Dawntrail to 7.3 left no room for surprises. I shouldn't be able to predict the future locations and trials several patches in advanced simply based on how closely the story is following a previous game.
