WLK has a nice look to it, I think, so the abbreviation is good. No big surprise here at all. 1up has the full details on the upcoming expansion, which is going to be the cover story on the next issue of Games For Windows magazine.

The biggest news for existing players is the introduction of the Death Knight, the first new class since WOW’s launch — and, coincidentally, its first Hero Class, too. Other big new features include the introduction of siege weapons and destroyable buildings in both a new Battleground and a brand-new outdoor PVP zone. What Wrath of the Lich King won’t have is any content for new characters: no new races, no new level-1-to-20 zones back in the old world, and little change to the old world.

Update: The official Wrath of the Lich King site is up. A panel at Blizzcon is offering up a few more details on the thing. I like this a lot:

So where’s our Shattrath? DALARAN!!!! “This place might look familiar.” It’ll be the home city for Northrend, so it’ll be on the move a little bit– shows funny animation moving the Dalabubble up there. Kirin Tor are setting up the final fight against the Dragonflight– they’re moving Dalaran to take a stand. It’ll be the home city, and floating above the air, access it from the ground… or flying mounts. Very centrally located in Northrend– we learned a lot from Shattrath, but build in a ton of lore and make it a really cool place.
