Not sure what to make of this expansion as of yet.

I like the move to Northrend, I like the sound of the new profession, and the hero class looks pretty sweet. But how soon will be too soon for this expansion to be released?

I don't expect Wrath of the Lich King to be released in the next 6 months personally, and I hope it isn't near that soon. As a casual player, I've barely touched Outlands. I still have three zones that I've barely touched and a number of instances...
