Ahem. Without further input I'm currently betting on Meracydia. Further down in the interview Yoshi-P says we should "get a refresher on Heavensward" as a hint to what's coming next. Aside from Meracydia being the home of Bahamut and Tiamat, pretty much everything on Azys Lla is either explicitly or implicitly Meracydian in origin. One of the driving forces in Heavensward was "dragons," so the general idea is "more dragons" - where better to go than the homeland of the franchise's two most prominent?
Sharlayan is more of a long shot, since it wasn't very prominent in the story. We did go to their abandoned colony out in Dravania, but other than the Great Gubal Library and Matoya's presence, excepting optional content like Eureka.
As Yoshi-P implies, expectations will be subverted and Garlemald is not on the table.
As for what's going to happen, I don't have enough information to reach any sort of hypothesis. The only cosmic-level threat on the table right now is the Sound that would have destroyed the world if not for Zodiark's creation. Zenos will continue to be a thorn in our side, but more worrisome to me is the enigmatic figure now serving as his accomplice. Said figure claimed to have knowledge of the Final Days, albeit "mostly secondhand."
There just isn't enough information to reach a conclusion one way or another, if you ask me.
