World of Warcraft Creative Director Alex Afrasiabi confirmed today on Twitter that Gorgrond and Talador are "on deck" with the Spires of Arak and Nagrand close behind. Currently, only the Tanaan Jungle introductory sequence, Frostfire Ridge, and Shadowmoon Valley are available for testing. Whether or not "on deck" means in the next build, we aren't sure, but we do hope it will be soon.
Gorgrond and Talador are on deck. Spires of Arak and Nagrand to follow closely thereafter. http://t.co/oOE7QJRCu5 when we have more info!- Alex Afrasiabi (@Abrosiabi) July 14, 2014
From what we know of these zones, the Blade's Edge Mountains of Outland were formed when Gorgrond and Frostfire Ridge collided in the shattering of Draenor. Early release screenshots, as seen above, also suggest that part of what became Outland's Zangarmarsh is on the outskirts of Gorgrond. Talador is a central zone in Draenor and is known to us as Outland's Terokkar Forest. Talador includes Shattrath and Auchindoun. We suspect we can expect a distinct orcish flavor in Gorgrond and Draenic in Talador.
