Disney has launched it's site for the upcoming film, which includes conceptual art, the first trailer, and images of the movie poster. There's not a whole lot there that hasn't been posted here before(outside of some new conceptual art), but I'm sure it will be updated soon with the second trailer. You might want to bookmark it and check-in from time to time.
