I didn't bother to read the whole post, and if this has been mentioned before I'm sorry for the double..
I was just questing in Darkshore as a ally druid, and it seems Azshara plays a little role there setting up a distraction for Stormrage.. So she actually is a little active in Cata (or pre-Cata) but how much more we'll see of her remains to be.. seen >.<
