If you were hoping Meracydia was going to come soon, Yoshi P confirms it isnt.

Meracydia gives an impression of a place Erenville would want to explore on his journey to see everything there is to Etheirys, but a bit too hard of a project to take on as a first one, considering how cut off the island is from the rest of the world. So if it happens, I'd probably expect it in 9.0 at the earliest, with 8.0 being something more reachable. There's still the north and some lands in the east that we didn't explore. Dalmascan region post-Garlean Empire could be interesting too.

I genuinely think the areas around Garlemald are finally going to be uncovered next, so we can finally see all of Ilsabard.
