Along with some (damn nice) concept art, there's additional info on customization of your character, followers, and perhaps a personal castle. (Copy-pasted some info from Kotaku)
Character customization will return "in a big way" for Dragon Age III according to a BioWare panel spilling details and concept art on next year's game at the Edmonton Comic & Entertainment Expo today.
Creative director Mike Laidlaw said that "customization is going to be bigger than Dragon Age Origins," to include "follower customization," according to producer Cameron Lee's live-tweeting of the event.
Asked how much control players would have over their character, lead writer David Gaider said "You will be human," before adding that "backgrounds will be in Dragon Age 3 even though you will be human, it's not playable but it does significant impact on the story." That again was according to Lee's twitter feed.
Other details trickling out suggest that you'll be able to take control of your own castle, and that the game will import prior character choices but, said executive producer Mark Darrah, "we're investigating some ways without save imports."
Edit: Another quote from the same panel:
Cinematic designer John Perry also stated that "he's had a longer pre-production on DA3 than any other BioWare project he's worked on". Perry also mentioned that "just one level in DA3 is as big as all of DA2's levels combined".
So any thoughts on this? Personally I was extremely disappointed in Dragon Age II, but I know some consider it to be perfectly fine. Apples and oranges, etc. Still, I have high hopes in this entry, and I really hope Bioware will make improvements necessary to the franchise. Also, I find the release date (Q4 2013) to be interesting, since most signs point to us having new consoles from Microsoft and Sony by then.
