Wrath of the Lich King, Deathknight, and then..?

So unless something drastic happens during the final fight with Ner'zhul/Arthas/The Lich King, this expansion will tie a lot of loose ends in the series storyline. With many of the villains of the series either slain or dealt with, what would be left? A surprise resurrection from Sargeras?

I'm curious of what YOU think. Where do you think the storyline should go once Wrath concludes? Deathwing is probably what they will shoot for I think, especially introducing the Chamber of the Aspects in this current expansion.

So please leave a comment explaining where you think WoW will go from here. The best theorycraft gets a free cookie.
