Whoa, slow down a second, buckaroo. First off, the Aerosmith coaster had a Star Wars overlay specifically for the paid opening night party ONLY - a PRIVATE event. As for what the overlay was - you were a guest, getting into a limo taking you to the premiere, and the limo driver had the music on the radio to get you in the mood for what you were going to see. Appropriate for that night, NOT a permanent replacement. The park isn't going all Star Wars (in case you've forgotten, there's a major Toy Story themed expansion in the works as well). Maybe a little more breathing before you panic might help.
