Cataclysm - 'The World Reborn' trailer

See how Azeroth's been transformed in preparation for WoW's third expansion

Here's a video showing off some of the major changes to World of Warcraft's Azeroth ahead of the launch of the Cataclysm expansion on December 7.

Blizzard unleashed a major update last week getting everything ready for Cataclysm's arrival. Patch 4.0.3 transformed Azeroth with a complete redesign of the Eastern Kingdoms and Kalimdor areas.

The full release of Cataclysm will raise the level cap from 80 to 85, introduce the Worgen and Goblin as playable races and add a number of new dungeons.
