Rabanastre and Dalmasca have had name-drops since 2.0 (2013), but actually including anything related to them in the game aside from a name-drop homage has been pretty recent (decided 2016), which is why it swung a bit of a wrecking ball through the story.
To give you an example, Dalmasca has now fallen to the Garlean Empire twice. Once in 1517 in Ilsabard, and once in 1547 in Othard. And Livia was known as the "Witch of Dalmasca" for her ruthless performance in its subjugation despite being too young to have been at either, regardless of whether she's supposed to be 26 or 28 (because the lore book assigns the higher age to the sister it labels "younger" and vice versa). Clean-up has been in progress since Return to Ivalice began, with concrete clarification that the latter date and location of Dalmasca's fall are canon and that Livia was more recently sent to put down a rebellion. I assume lore book deux will clean up some of the loose ends...
So to bring it back around to your question - I do suspect we may get more than just Garlean territory, but whether the rest is Dalmasca based on its significance in Return to Ivalice and recent mentions in the MSQ (Thancred name-drops it for example) I'm not sure. We'll be able to gauge their intentions much more readily after we've seen whether Matsuno successfully liberates Dalmasca (his stated goal) and brings the chapter to a close in Raid 3. Though, as Bright-Flower said, the capital has already been razed to the ground. No unringing that bell.
I've been suspecting Thavnair to be the second area, but that's what I said when they added the Far East instead, too, lol.
