Midgardsormr and the Airship in Mor Dhona!

[Alaltus]

I don't think they'd remove something that everyone in the game went to take screenshots with at one time or another... at least I don't think they would. That concept art with a destroyed Isghgard-looking thing makes me nervous, but the new bestiary entries say the wyverns are on the front lines attacking them so I guess the city is still there.

I wonder if they built that Rapture bar I tried to rally for! (lol)

There was an interview where it was brought up i'm sure, not sure where but Yoshida said that it was a Ishgadian Fortress that was in ruins and that he felt he had to implement Ishgard into the game like Musketeer etc

I'm hoping Migardsormr and the Agrius will still be there, though what will happen with Agrius if it is? It's weaponry is still functional judging by the end of the original 1.0 questline.
