DA:Inquisition - New DLC Descent

Bioware announced today that they will release a new DFC for this game, named The Descent on August 11th of this year for PC, Xbox One and the PS4. The Descent DLC takes us back to the Deep Roads:

In Dragon Age: Inquisition - The Descent, you will venture deep below the surface to discover the source of mysterious earthquakes threatening Thedas. Explore the legendary Deep Roads, but ensure that you come prepared. A perilous journey awaits underground, where vast, darkspawn-infested caverns will challenge the Inquisition like never before. Meet memorable new characters, learn more about dwarven history, and collect epic loot as you fight to solve one of Thedas's greatest mysteries. 

Thanks to Dutch's Ghost at the Bioware DA:I forums for finding this.
