The German (we truly do love using this word) Unterhaltungssoftware Selbstkontrolle (USK) ratings board, their equivalent of the ESRB, has rated a game called “World of Warcraft: Wrath of the Lich King (GC-Demo)” for ages 12 and up. The rating was given on July 30, 2007 and the title of the game pretty much gives away that it's the name of the next WoW expansion. The demo was probably given to the German ratings board in preparation for Leipzig's Games Convention in three weeks – so those who couldn't get their tickets for BlizzCon, there's always Leipzig.

This bit of information alluding that the next WoW expansion will have players going to Northrend goes with mounting evidence gathered by WoW Insider and the rumor that the Video Games Live orchestra will be playing pieces titled “Northrend” at a BlizzCon concert. Considering the fallen Prince Arthas from Warcraft III is the Lich King who sits on the Frozen Throne in Northrend, we're going to take a leap and say that WoW players will be exploring the lands to the north once this expansion hits … you know, whenever that is, ‘cause it’s Blizzard and any guesstimate of a date would be pointless.
