Is Cataclysm the Next World of Warcraft Expansion?

There has been no official announcement yet, but a number of moves by Blizzard Entertainment seem to indicate that the next expansion for World of Warcraft could be titled Cataclysm. Speculation began when Blizzard trademarked Cataclysm recently, and then later when a test server briefly popped up with the word 'Maelstrom' in its name. If true, the name would fall neatly into the WoW lore and expected expansion list. The Cataclysm is another name for the Great Sundering, an event that created a swirling vortex of water and mystical energies (the 'Maelstrom') that has appeared on the world map in-game since release. There are also indications that early design work included some of the islands in this area, which has long fueled anticipation of a Maelstrom-based expansion involving the former Night Elf noble, Azshara, queen of the Naga and the Goblins whose main city is in the south seas
