When was the last time we saw Arthas? Warcraft III: Frozen Throne? Well, since the announcement of World of Warcraft: Wrath of the Lich King, it looks like we'll be seeing a whole lot of the corrupted ex-paladin.

Along with the Arthas-Ner'zhul combination comes a number of new stuff for the new expansion from Blizzard: higher level cap, a new content, and a new hero class. We're sure you're all excited about all those things, though not everybody was there at BlizzCon when World of Warcraft: Wrath of the Lich King was announced. Don't feel bad though, as we do have the trailer as shown at the convention.

We'll leave you to it. Arthas gives his challenge to all who dare enter Northrend in this Wrath of the Lich King trailer, so go on and press play. Enjoy.
