Rumor has it, the world as it is now will change from patch to patch. New missions will be added and old ones will be deleted as the story progresses. A new player six months from now may or may not play in Kingsmouth as it is today. Funcom has said the storylines of the Savage Coast will progress.
Differently solves the problems WoW has with old story's like TBC.
Maybe Funcom has learned from their AoC mistakes?
