I hope you are right but I just have a feeling that Avatarland and AK will end up being the big winner out of all of the "expansions", in part, because of James Cameron teaming up with Disney's Imagineers. Under Cameron's guidance, the Imagineers will finally be free to exceed the nickel & dime boundaries and stipulations that Disney unfairly imposes on them.
Disney has become somewhat reactive instead of proactive.The only reason for the New Fantasyland expansion is because of Harry Potter, otherwise we would only have a Pixie Hollow meet and greet. Diagon Alley, Transformers, Despicable Me, and Simpsons expansion didn't rock Disney the way others claimed it would. And, Iger only promised a strong Star Wars "presence" in Disney Parks.
There is enough room for a decent Star Wars Land and plenty of amazing details. So, we'll see. Two really nice Star Wars themed rides can fit nicely back here and of course a restaurant or something. I just hope TSPL is completed by late summer of 2016 or before Avatarland.
