They may be testing "Cars" presence in DHS still. Sure, they need more kids attractions, and more to do on the opposite side of the park to keep people busy when not at Star Wars...
But I wonder internally if they're still trying to decide which property to build a land/ride for next... Hopefully, bulldozing all of Animation Courtyard (instead of retrofitting worthless walk-throughs in its weirdly shaped structure,) along with Little Mermaid and Disney Junior. That area is a good chunk of land... And I bet you someday, (maybe 5, 10, or 15 years from now lol) we see another Pixar property take it over.
