Further more the Death knight will be made available to all races currently in the game. The death knight will be a new class just as There is Human Mage there could be Human Death knight, as an example. The revered reputation to get heroic keys and attunement will not change. the conflagrate bug will be fixed in patch 2.2 As it is the icon is still being displayed and conflag is not being consumed at all.
As a last note, at some point in the future we should see Surnames as well. However this could take long to implement :)
