Yes, but of course Splash was IP as wellSome of their best attractions over time were non IP. Expedition, Everest, the haunted mansion, pirates of the Caribbean, Spaceship Earth and all of the original Epcot rides, Space Mountain etc.
Disney also said "dozens" of animatronics, and reliable sources are saying over 30.Additionally, this seems to be a half budget makeover of the ride with less animatronics and more screens
