I think they need to utilize the early 2000s IPs and mid-late 90s IPs more before they put stuff in that hasn't really stood the rest of time.
WDW doesn't have a confirmed ride for The Lion King, nothing involving Lilo and Stitch, nothing substantial for Aladdin, Hercules or Mulan, all Beauty and the Beast has is a restaurant. On the Pixar side they've got nothing with The Incredibles, WALL-E is the most EPCOT Pixar film ever and hasn't shown up yet, Emperor's New Groove has it's fans.
Sure nobody is dying for Chicken Little to get a major ride, but I think that list alone would be good enough? I'm biased here but my age range, born around the early 2000s and such, are going to be looking at increasing spending power in the near future, it makes Disney would want to monopolize on things that my generation has nostalgia for. I carry bias here and I'll acknowledge that, but I can't necessarily disagree with them on wanting Monsters Inc and Cars in Florida in a more expanded manner, even if they way they're doing it is destructive.
