Weapon (d4)

Yes, and they are planning two more expansions for WoW...

Considering the fact that the strength of the enemy is increasing, they will definitely give us another chance to fight against Kael'thas, kill another ancient god, and face the real Ner'zhul (Blizzard has said that his story is not over yet), as well as the reborn Kel'Thuzad and Kael'thas Sunstrider (again). It is also possible that Sargeras will suddenly appear from "who knows where".
