Dragon Age: Inquisition is an upcoming sequel to Dragon Age: Origins and Dragon Age II and is currently in development by BioWare. It was first (informally) announced on Twitter, the evening of May 19, 2011, by BioWare's Creative Lead Alistair McNally. It was then formally confirmed as Dragon Age III: Inquisition on September 17, 2012 in an open letter by Executive Producer Mark Darrah. It was revealed during Electronic Arts' E3 2013 press conference that Dragon Age: Inquisition will be released in the fall of 2014. The game is set to be released on PlayStation 3, PlayStation 4, Xbox 360, Xbox One, and PC.
Combat is also expected to differ somewhat from its predecessors and focus more on a player's ability to prepare, position and form a cohesive team with his or her party members, requiring fewer repetitive finger strikes but better thinking. The armour customisation will differ from both Dragon Age: Origins and Dragon Age II, in that each party member will have interchangeable armour pieces that will customise the look according to its specification and class. They will also refrain from reusing environments, a common criticism of Dragon Age II. Cinematic designer Jon Perry said that "one level in Dragon Age 3 is as big as all of the levels in Dragon Age 2."
Ray Muzyka, the CEO of BioWare, said in an interview with Wired.com that Dragon Age: Inquisition would be influenced by more open world games, such as The Elder Scrolls V: Skyrim, which BioWare is "checking out aggressively."
BioWare will use a brand new engine which will use Frostbite 3 as a foundation.
It has been confirmed by David Gaider that the Game will feature "multiplayer in some form." It is not known yet what the Multiplayer element will be. 
Producer Cameron Lee has implied that there may be some form of "castle-controlling" mechanics.
The game will have creatures new to the series.
Regarding character creation, the advent of multiple playable races will by necessity require different body and armor models for the protagonist. This aspect, according to Mike Laidlaw, will furthermore take precedence over any potential body shape choices or sliders in the Inquisition character creator.
Although touted as an "open world" game at E3 2013 presentation, the developers quickly clarified that Inquisition will not be open world in the same way as The Elder Scrolls V: Skyrim, but instead simply feature larger locations (than presumably Origins and Dragon Age II) with more exploration freedom.
It is the first game in the series to feature mounts. 
The protagonist of this installment will be known as the Inquisitor, following the player characters of previous two games of The Warden, The Warden-Commander, and The Champion.  As was the case in Dragon Age: Origins, players will be able to choose from three playable races for the Inquisitor, and the game will recognize race flags, class flags, or a combination of the two depending on the situation.  Mike Laidlaw has stated that playing as a different character "does not mean your old character may never appear in future games," which could indicate that the new protagonist will be able to meet Hawke and the Warden (provided that the latter survived the events of Dragon Age: Origins).
The game will be set in Thedas, and it has been heavily implied that the game will be set primarily in Orlais. The game will cover more geographic territory than its predecessors, with one map being described as four to five times the size of Ferelden, the setting of the first game in the series.
BioWare mentioned that the main plot will be "saving the world from itself." The plot will involve an all out war between mages and templars, the foundations of which comprise the main plot of Dragon Age II. Along with the larger size of the game map, the player will be able to travel to countries such as Tevinter to calm or encourage the fighting.
According to Dragon Age writer David Gaider, the story of the Warden "is over" and Hawke's was continued through Dragon Age II downloadable content. The story in Dragon Age: Inquisition will be much more open-ended than the previous games.
Laidlaw also confirmed the ability for players to import their save files, or alternatively their "world-states," from the first two games into Dragon Age: Inquisition to "shore up world consistency." Mark Darrah later stated that BioWare is looking into creating ways to include choices made in previous titles without the need for a Save File transfer system, as well as a method to import save files across console generations.
According to Mark Darrah, for players who do not have or choose not to import a world-state into Inquisition, a default "canon" will be provided as in Dragon Age II: an "Ultimate Sacrifice" Dalish Warden, Alistair made King, and Hawke a mage who sided with the mages in DA2. He indicated as well that choices from Awakening will also impact playthroughs.
The subtitle Inquisition has been previously hinted by the Dragon Age 2 strategy guide's epilogue, which asked "Will some kind of inquisition be at the heart of events of the next Dragon Age title?" David Gaider has also said, "It'd be interesting to see if the Inquisition ever rose up again."
