Kylo Ren made his debut at Disneyland yesterday, and like Vader... he talks! Unfortunately, I believe he has replaced Vader. Hopefully they will rotate them out like normal characters once the Episode 7 hype dies down. Not gonna lie, I'd love to see Kylo waiting in line to meet Vader... it would be hilarious.
As for Captain Phasma, hopefully she never shows up at Disneyland. Its bad enough the character was thrown into the movie only because JJ Abrams was a fan of the actress.
In regards to Star Wars Land itself, while I'm excited & can't wait for it to be built... I have this sinking feeling that it won't be as great as it could/should be rides/attractions-wise. So far from what they have released doesn't exactly make me say "OMG ITS GOING TO BE SO AWESOME!!!!". I got that kind of reaction from the "Hyperspace Mountain" overlay, but NOT the Millennium Falcon ride/attraction they keep trying to hype up. I have a feeling part of that has to do with the fact that its just another simulator type of experience. While I know I should expect that from a franchise like Star Wars which is comprised of so many different worlds, I feel like they already have that type of ride covered with "Star Tours", which is pretty much perfect (except for the fact that Finn is flying the Falcon in the new Jakku scene & he isn't a pilot, hence his reason for needing Poe in TFA).
I remember Disney saying that they were shelving all of their Star Wars ride/attraction concepts so they can create new ones based on the new movies... Honestly, that is a bit unfortunate because as I mentioned before, they have an X-wing/Tie-fighter coaster concept that was never built at DHS. Considering, we have both types of ships in TFA, I don't see why that concept couldn't be used still. Just think of THAT dueling coaster concept, but with the overlay they used for Hyperspace Mountain!
I do have to wonder though, what will happen to Star Tours & Jedi Training Academy in Tomorrowland when this new land opens? I figured they plan to create a new permanent Jedi Training Academy location in the new land, but again... what will happen to Star Tours?
