The release of a new World of Warcraft expansion is one of those events that's going to be huge whether or not it gets hyped up. Nonetheless, Blizzard is adding to the pre-launch excitement with a new trailer.

The trailer is entitled "World Reborn" and showcases the new locales of the expansion. While Cataclysm marks a return to the Kalimdor and Eastern Kingdoms continents from "vanilla" WoW, the old lands have been redone with new terrain and new quests. Previously inaccessible territories like Gilneas and Uldum have been added to the map as well.

The Cataclysm expansion will go live on December 7th. Check out the details on GameStop's midnight launch events if you want to play as soon as the expansion goes live.
