I don't think it is real as far as an expansion goes. Maybe a major patch? They already said it was weird to be fighting deathwing to level 60 then hop to outlands and for 10 levels you are suddenly up against Stormrage and poof, back to the whole deathwing bit again.

Also I am pretty sure A'del is a race not a NPC, and with no new race/class why have new starter zones?
