Wrath of the Lich King Twin Airships flying over Icecrown!

I saw this video a while back but lost the link, just now I found it again after renewed excitement. As you know from my post earlier, the Beta Realms for Wrath of the Lich King are going down for a new build and maintenance. This map of Icecrown was spotted and I can’t help but smile when I see an Alliance and Horde airship on the map itself flying in an attack pattern over the citadel where Arthas (and the final raid of the expansion) reside.

Flying fortresses.

Alliance – The Skybreaker
Horde – Ogrim’s Hammer

Possible quest hub or actual battle field in the skies? What do you guys think?
