I do not think Universal is interested in giving up the rights and Disney cannot muster up a deal to Universal to get them to let go of the rights. Bluey is just what's going through my head since, well, another poster there did make a good point, why replace the only young child fare in a park hurting for it with more things that'd need height limits?
As I said in the Rumor Tracker, last I heard was mid-24 with Zootopia and Simps being thrown around. There's the rumors that Universal apparently is spitballing removing MSHI but IOA has bigger issues (Toon and LC) as of now, so I find it unlikely Universal will give up that until Lost Continent is redone, Toon is redone, Simpsons is gone and replaced with Pokémon and something is done with World Expo, along with expanding Epic Universe (Dark Universe and HP specifically).
I drew the conclusion of Bluey based on logic, something this company hates, so for all I know, Disney has decided on Herbie the Love Beetle land.
Here's the main issue with a land based off any preschool IP, those IPs typically have time limits, of sorts. They take over the world for awhile and then vanish with the wind. Will Bluey be relevant in say, 2030?
