There's still no release date set for World of Warcraft: Cataclysm, but Blizzard announced during GamesCom 2010 a limited Collector's Edition for the next expansion. It will retail for $79.99.

This edition will include the following extras:

* Art of the Cataclysm art book, featuring 176 pages of never-before-seen images from the archives of the Blizzard Entertainment cinematics department and the World of Warcraft development team, as well as progressive visuals from multiple stages of development.

* Exclusive in-game pet: he may not be a breaker of worlds just yet, but Lil’ Deathwing will still proudly accompany heroes on their struggle to save Azeroth from his much, much larger counterpart.

* Behind-the-scenes DVD with over an hour of developer interviews and commentaries, as well as a special Warcraft retrospective examining the rich gaming history of the Warcraft universe.

* Soundtrack featuring 10 epic new tracks from Cataclysm, including exclusive bonus tracks.

* Special-edition mouse pad depicting Deathwing menacing the ravaged continents of Azeroth.

* World of Warcraft Trading Card Game cards, including a 60-card starter deck from the Wrathgate series, two extended-art cards, and two Collector’s Edition-exclusive hero cards, marking the first appearance of goblin and worgen heroes in the TCG.
