Via the fine folks at RPS, a wiki with more Lich King info than you can shake a stick at. I do love the British sense of conflicted humor:

There’s a hell of a lot of minute detail on supposed new skills and talents in there, which will doubtless prove the most thrilling element of this enormo-leak for dedicated WoWians, but those of us who care about more than the numbers can enjoy all the screenshots of new monsters and armours and the like. How Arthas, fallen prince of Azeroth and current Lich King (and WOTLK’s Biggest Bad) appears is in there, as are cutey-wutey clockwork gnomes, a possible demon form for Warlocks and Tauren canoes. We even get to see what Gnome Death Knight looks like. My main character was a Gnome. I could be a Gnome Death Knight NO STOP IT NO NO NO.
