Namely, Cinematic Designer John Perry said that "he's had a longer pre-production on Dragon Age 3 than any other BioWare project he's worked on," and that "one level in Dragon Age 3 is as big as all of Dragon Age 2's levels." Creative Director Mike Laidlaw noted that players will be human in the game, and that "customization is going to be bigger than Dragon Age: Origins."
BioWare GM Aaryn Flynn posted a picture to Twitter of the backs of event attendees' heads, which happened to include concept art for the game in the background. As nice as those heads are, we will update when the actual art is available. Dragon Age 3: Inquisition is in development and slated for a late 2013 release.
