An official confirmation has been given by Disney when it made infrances about theme park happenings among the galaxies taking place at the upcoming 2013 D23.

Dave Fisher is said to have said that they are working on Star Wars and Avatar attractions for the parks division. My personal thoughrts are that Disney has planned all along to have significant announcements/presentations during D23, but are slowly building up excitement and anticipation by dropping information a little at a time.
