It appears that a potential leak of information about a forthcoming DLC for Dragon Age: Inquisition has been leaked via a survey sent to game owners. The survey indicates that it is the "final fate" of the Inquisition, it is also said that "you will embark on the last adventure with your team" against the Qunari.
The information contained in the survey was leaked on the Bioware Dragon Age: Inquisition forum.
