It makes Universal a lot of money, and more than ever on the property that already did.But universal is literally giving Disney money & free advertising by keeping it. lol. It makes even less sense for them to keep super hero island in the long term when it isn't their own property. (I.E - Simpsons going away.) I understand it is under different circumstances than simpsons land. But even if they have the rights in perpetuity. Why would they continue to advertise disney properties in their parks. When instead they could use the space for their own IP.
Makes perfect sense to keep it.
By the time Universal sees fit to give it up, it won't be worth theme park lands.
Universal's Marvel take wound up more timeless and encompassing than anything Disney has done yet.
Nothing of their own IP right now would do as well as MSHI.
It features all time greats in IP and theme park design.
