An anonymous reader writes "Wrath of the Lich King is official! BlizzCon is in full swing, and celebrants there are already enjoying the Northrend-themed imagery. For a look at what's going on, Joystiq has a liveblog of the opening ceremony up. Games For Windows magazine, meanwhile, will feature WLK its next cover. The post on the 1up site has a number of details on the next expansion, including the introduction of the Death Knight, the first new class since WOW's launch 'World of WarCraft's first Hero Class is a plate-wearing tank/DPS hybrid that works a little something like this: When players hit level 80, they'll be able to embark on a quest (similar in difficulty to the Warlock's epic mount quest, back before the level cap was raised to 70) that unlocks the ability to create a Death Knight character. The Death Knight starts at a high level (somewhere around 60 or 70, though Blizzard isn't certain yet), so you won't have to grind your way back up all over again. It's intended as an alternative, advanced class for end-game use only.'."
