That'd be pretty neat. Idyllshire looks like it's going to be fairly large with a lot of buildings that can be explored so it'll be interesting to see what flavour text/NPC's and fresh services will be added there.

I'd also quite like to see a return of the Moogle Delivery quests to have us 'catch up' with some of the forgotten NPC's strewn throughout the 3.0 zones. We'll also likely see the conclusion of the Scholasticate quests soon too.
