What do Dark Iron Dwarves have to do with Kul'Tiras?

I think they won't unlock at the same time, they were just the two post-release races that were both definite and ready enough to be shown at BlizzCon.

Sounds like someone in Blizzard got bit by a bug that gave them an itch for something unnecessary.

Best way to describe the possible inspiration behind this idea.

There will be a Dark Iron keep on Kul'Tiras being assaulted by the Drust or something like that.
