With World of Warcraft: Cataclysm in stores, Blizzard revealed some info on the future of its acclaimed MMORPG.

A fourth expansion was finally mentioned officially, and according to Greg Street - systems designer at Blizzard –, Eastern Kingdoms and Kalimdor are good the way they are, and they may go for “something more like a new continent approach. More like the Burning Crusade or Nothrend, where we send players somewhere new that they haven't seen before," he said to CVG.
