I think that Ilsabard has been mostly destroyed. I'd still like to go there, but I think it's pretty cut and dry that most of it is in ruins. Not really wanting, "Bozja The Expansion" more or less. Even though I do like Bozja. If they do anything noteworthy with Ilsabard, it's likely that the Garlean capital will turn into a "primal" city, based off of Pandemonium from FFII.
The empire doesn't really hold a lot of interest for me anymore. The stakes we've had with the Ascians were always higher, and beyond sheer numbers, the Empire itself isn't really much to write home about. All of their coolest shit, they bring to bear on Eorzea anyway, and I'm much more interested in Sharlayan.
I think it'd be cool to have the Underground as a proper zone with a city and a tower of Babil reference. That's what leads to the Moon in FFIV, and there's also another way they can reference Alexander with the Giant of Babil's original concept art.
