I made this back in 1.0 but to serve as a reference. Those are the only areas in which I can think were not in the 2.0 (the south part of Eastern Thanalan was obviously ruined by the calamity (which is now the area with the mirrorknights) instead they gave access to a completely new area (south thanalan proper) with the desert and the Am'ja stronghold.

The other half of Mor Dhona just simply "vanished" it doesn't look to wrecked when you look across the lake but still cannot access. West Shroud just up and disappeared, I assume calamity destroyed most of it because the zone line from C.Shroud to N.Shroud has dead trees and no grass as if something wrecked it to hell and back. Which leaves us with the old "southern" portion of Coerthas that magically disappeared, as the lake doesn't exist anymore, however it in that portion of the map where Darkhold or Aurum Vale was, iirc, so unless Darkhold/Aurum Vale magically moved more north then the southern part of Coerthas is already included but has suffered from massive geographical changes.

All in all it just seems that the only two places they could add that were existing 1.0 places would be West Shround, Southern Eastern Thanalan or the other half of Mor Dhona.
