I feel like once Dinoland closes fully and Zootopia arrives, the park will truly be theme-less, or at least a thematic mess.
Animal Kingdom's themes are conservation, the power of nature (animals and the environment) over human constructions and existence, and transformation through adventure and discovery (getting a "personal call to action"). Also, Animal Kingdom needs animals of the past (1), present (2), and fantasy (3) to meet its remit.
When Everest and Pandora arrived AK had finally fulfilled all 3 of its animal criteria. Now that Dinoland is going we'll have no animals of the past, and in fact the Tropical Americas is only going to oversaturate the park with fantastical animals. We know now that the small animal exhibits have been cut for a playground there so that sucks, and its not like we're gonna be a non-IP extinct wooly mammoth ride anytime soon, so the park is back to missing some of its animals.
Zootopia in no way matches any of themes mentioned above (conservation, nature over humans, personal growth through discovery), and in fact it exists to overwrite the presents of insects in the park, an extremely important part of the real-life animal kingdom and circle of life.
IMO we need a Zootopia Tree of Life replacement ASAP (I know we're not getting one for decades though), some new extinct creatures presence in the park (I'm thinking not dinos but maybe wooly mammoths or something), and the protection of existing animal exhibits in the park (don't let Kilimanjaro lose animal enclosure space to future expansions!). Oh and add some animals to the Tropical Americas please haha. We used to have crocodiles there during Dinoland times.
