DF is pretty non-cosmic we have been to the emerald dream several times already. And most hints at agrander cosmic storyline like the Elun'Ahir stuff is dealt with in background lore books. We are only dealing with very close "Azerothian" threats.
Of course a Revamp would be great, and with the assets in the files, i am sure Blizz is working on it in the background, but i think they want to do it justice and it a massive project. I am fine with exploring new places in Azeroth, while the revamp is in progress. I just don't want to travel to the life-, order- or voidlands anytime soon
