Blizzard has published talent calculators for World of Warcraft: Wrath of the Lich King, enabling budding fans to pre-emptively plan level-80 class builds. To kill level 80 rats.
Of most interest will be the entire set of Death Knight talents, although Blizzard reminds us each tree is subject to change whilst the beta test continues. A "last updated" time-stamp is displayed on the official page to help make this a little less confusing.
Blizzard plans to release the second World of Warcraft expansion pack sometime between October and December this year.
Alongside bundles of additional content, Wrath of the Lich King will improve shadow, shader and draw-distance capabilities; Blizzard recently said this would mark the beginning of an iterative and organic approach to overhauling graphics in the soon-to-be four-year old MMO.
