If you are waiting for the first, official, and concrete information about Dragon Age III than you need to be patient. Very patient. According to Chris Priestly, we would not get any new info about the game this year. Priestly said, that until the team responsible for the game is not ready, they will not tell anything. The comment in the extension.
As I have said before, we will not be discussing DA3 until, likely, spring next year. There won't be teasers or other info until Mark Darrah & the team are ready to open the gates and actually start talking about the game. Sorry.
Attention: Information can appear later.
And Fall is a best guess at the moment. The game has been in the works since the end of DA2, and things are going well, but it will take as long as it needs to. Fall next year (sometime between Sept & Dec) is a good guess, but it could be longer if it needs it.
