Confirmed!
Well, if the trademark application and all the buzz was not enough, here we present a picture of what appears to be a brochure or program from Blizzcon. From it we can gather a fair bit of info.

- The dark, necromatic Death Knight – the first new character class added to World of Warcraft since its launch.
- Northrend, the harsh, icy continent where the Lich King holds rule, complete with new zones, quests, items and monsters.
- New level cap of 80 providing access to mighty new powers and talents
- New battlegrounds featuring siege engine warfare and destructable buildings
- Expanding character customisation options including new hairstyles & dances, the ability to change the hairstyles of existing characters, and new skin color variants.
I’m sure more info will be pouring in as Blizzcon continues so be sure to check back
