It's..a somewhat fair point to consider, considering the Barry Jenkins project at the Live Action department moving forward. But yeah; there's other IP that would be more likely for investment than that.
I've been on the Indy South America train for a while, only for a few reasons.
One being, Disney's past in wanting to retheme attractions leading itself well to have them excuse retheming Dinosaur into something it wasn't meant to be; and adding animals and wildlife from the region to Animal Kingdom. I'd even take a Harambe like area in that situation.
But yeah, I'd bet Zootopia. I don't want it, but corpo probably sees it as the more potential financial success on a merchandising front; assuming Shanghai is a success as you said.
