IF this does happen, what is everyone's wishlist for SW and Cars at DHS? Do you want them to replicate CarsLand exactly from DCA to DHS?
My thoughts -
CarsLand - I think it should be a bit scaled back, I'd be happy with just the town of Radiator Springs and the RSR attraction. Though I would want them to do the long rumored Monsters Inc attraction that is supposedly on tap for next to TSMM. I would think if that was in the cards, though, it would be opening soon, to coincide with Monstrous Summer and the prequel.
As for RSR, I would actually prefer for them to theme it more along the lines of Cars 2, just to give it a change from the original out in DCA. Granted, I've never been to DCA and the new attraction, but I think it would be nice to mix it up. I understand that Cars 2 is widely panned (I don't think its all that bad), but they have some great visuals to work with, with the Tokyo street scene, the Rainbow Bridge, Porto Corso and the Casino Bridge, and London in general with Big Bentley and everything else. They could use the different race cars from the movie as the ride cars, while still having Lightning and Mater alongside as props or whatever.
Star Wars Galaxy - I have given my plans elsewhere here, but it would include a large expansion and at this point, it isn't looking like that will happen. In lieu of that, I would definitely like to see the indoor Jedi Training Academy with the Turtle Talk technology (Yoda). I think a spinner ride is needed at DHS, and Star Wars provides the perfect fit, as there are many different types of ride vehicles they can use, whether its pod racers, speed bikes, x-wings, TIE Fighters, or even little versions of the Millenium Falcon. This would help address the lack of rides/attractions for the little ones who are under 40".
I agree the Cantina would be the logical choice for eatery, whether TS or QS, but I can see them going with a more general Star Wars theme. The Cantina wouldn't be quite the same without all of the aliens in it, and it would be difficult to create and maintain that many workable AA, and not exactly feasible to outfit CM's who are servers into the type of costumes needed to pull it off well. This would be another chance for them to incorporate the Millenium Falcon, as they can build out the facade of the restaurant to look like the great ship.
I have to think they'd want to add an E-Ticket ride in there as well, and X-Wing vs TIE Fighter attraction would be great, if they can come up with a good concept, or use the technology they patented for the wind-tunnel airplane attraction.
If what is coming out from the different sources is accurate, it doesn't seem like they are going to have separately themed areas for different planets, which is a disappointment. Would love to see a Tatooine area with Jabba's Palace, a PodRacer attraction, Mos Eisley Cantina, and M&G areas for Jawas, Tusken Raiders, Boba Fett, etc. A Coruscant area with the Jedi Temple (maybe the Sound Studio with a new facade) for the Jedi Training Academy, and Streets of America rethemed to Coruscant. A Naboo area with Theed Palace and Naboo Falls (E-Ticket ride similar to Matterhorn Bobsleds). The Death Star. An Endor area with a playground for kids to replace Honey I Shrunk the Kids area, and M&G's with various characters.
