If you read this article from blizzplanet.com they interviewed Josh Mosqueira on Aug. 25th and they said the Necromancer will play a role as either a NPC or possibly a playable character. But we will not know anything until Blizzcon so it is still speculation about using the necromancer as a character but they will have some sort of role.
