Official Death Knight Info

Blizzard has posted some information in the way of an interview with their design team. Here is a sample...

In Wrath of the Lich King, you will be able to pick up a runeblade, don some plate armor, and wreak serious havoc using both melee abilities and offensive magic. To give you an early glimpse at the design philosophy behind the new class, we sat down with the World of Warcraft design team to talk about the role the death knight will play in the expansion's story as well as in its gameplay, and to get their thoughts about goals and ideas for the new class.

You can read the interview and find out more about the lore here.
