Interesting news from Saturday afternoon's Diablo 3 Lore and Art panel at Blizzcon. During the question and answer session, D3 Story Lead Leonard Boyarsky was asked if we'd see any Necromancers in the game. To the surprise of the conference attendees, he said yes. That players will definitely see "one or two" Necromancers in the game, as NPCs or perhaps even as hireable mercenaries or some type.
It's long been known that the favorite D2 class will not return as a playable character, but this is the first time we've heard that they will make any kind of appearance in the game. Expect rejoicing from your local cemetery.
