I personally would rather see this be a phase 1 of a multi-phase Fantasy Springs type expansion with a dash of (a better done) Pixar Pier. I actually don't hate the Zootopia idea as much as most. And, I am not against the multi-IP land if done well. Monsters Inc., Zootopia and Incredibles could all easily be city-scape based, adding some level of continuity. And, I think that would be a compelling replacement behind Animation Court. Again, you could easily start with Monsters and build from there. It would even give a little conceptual throw back to the Streets of America area of the park.
Not saying it would happen. Rather something like that would make far more sense to me than cramming it into Grand Avenue.
