According to the recent Jim Hill podcast, the closed Innoventions West at Epcot will become a Star Wars museum temporarily in promotion for the Force Awakens in December. This begs the question, so what is going on in Disneyland's Innoventions? My guess it is the same exact thing. You will be able to see costumes and props from all seven movies.
My guess is there will be Star Wars meet and greets and may be a trailer will be put in the Captain EO theater. They could also put the Jedi Training Academy in there and free up Tomorrowland Terrace but my guess is it will stay outside.
You can hear this about the last five minutes of episode 81 of the Disneydish podcast.
