Speaking for myself only, my excitement for Avatarland has absolutely zero to do with the movie because I never saw it. I think the concept art looked amazing and if they can pull it off it's going to be a beautiful addition to an already beautiful park.
Agree completely. I really like Animal Kingdom, but it has always felt incomplete. Knowing the story behind the Beastly Kingdomme and the dragon on the original signs justifies that feeling. Before Everest, it felt even more like that. Like the Studios, it suffered from the "let's build the park halfway and let profits from the park pay to make it fully realized" concept that was a hallmark of the Eisner era. MGM, Animal Kingdom, Disney Studios in Paris, California Adventure,
Disneyland Paris, and Hong Kong Disneyland. Only DisneySea opened with a truly full slate of attractions during Eisner's tenure. The other parks were all crippled in some way.
Pandora finally will give Animal Kingdom that fantasy animal area it was supposed to have all along. I've not even seen Avatar nor do I care to, but the concept art Disney has shown is fantastic. I also look forward to the night show that will come with it, rumored to have some elements of the fountain show out at California Adventure, The Wonderful World of Color. Another land to explore, another E-ticket, and a nighttime spectacular. That will make Animal Kingdom complete finally - and the most beautiful of the parks (well, it already is that, but more so).
Though Pandora will highlight the problems at Hollywood Studios. It has already fallen behind Animal Kingdom in attendance and will probably fall way behind after Pandora debuts. Epcot still needs a lot of work too, but the festivals keep Epcot attendance in very good shape. Hollywood Studios needs more attractions - E-ticket and otherwise. It really could use an expansion as well to push up capacity.
Universal has the advantage of only needing to deal with two parks. Disney has four to worry about and can't spend big money at all four simultaneously. Even Universal tends to alternate. After Diagon Alley opens, expect to see USF not getting anything new for 3-4 years. IOA will be getting anywhere from 2-4 new attractions during that period, though USF will get some refreshes and upgrades.
