Update: 

Blizzard has posted an awesome and catchy cinematic trailer for Hearthstone: Blackrock Mountain. Who knew that Carlos Larkin, Blizzard's voice actor for its male Dwarf characters, could have such a great signing voice?

Original Story:

Ragnaros the Firelord and the Dark Iron Dwarves are back in Hearthstone: Heroes of Warcraft's new Adventure/expansion, Blackrock Mountain.

Blizzard Entertainment has announced Blackrock Mountain is going to be the newest raid for duelists to challenge in its hit digital card game, Hearthstone. Fans of Azerothian lore will recognize Blackrock Mountain as a previous raid in World of Warcraft just as they did for Hearthstone's recent Naxxramas Aventure. As expected, Blackrock Mountain will introduce all sorts of familiar bosses, dragons and nefarious dwarves for you to face as you explore its molten core caverns and get close to challenging the elemental Firelord, Ragnaros. It would be awesome if his weapon/hand, Sulfuras, drops as an in-game card for you to use. We'd love to see Emperor Dagran Thaurissan, Magmus, Lord Incendius and Ambassador Flamelash appear as a card or even as a boss battle. It would also be interesting to duel Queen Regent Moira Thaurissan Bronzebeard, since she's part of the Council of Three Hammers (Ironforge's Dwarven leaders).

The Blackrock Mountain expansion of Hearthstone: Heroes of Warcraft will launch this April for its PC, Android and iPad formats. Just like the Curse of Naxxramas expansion, Blackrock Mountain will be split into multiple wings, with each branch being released on a weekly basis. The entire Adventure/expansion costs $24.99, with each individual wing costing $6.99 or 700 in-game gold each. Pre-ordering (real currency only) Blackrock Mountain will begin on March 19, and you'll get an exclusive card in the game for doing so.

Never forget what Hearthstone can do to your friends:
