I'm starting to believe this. Alien has a great following among adults - an untapped segment of the market that Universal continues to use to grow its theme park attendance. This will fit right in with their strategy. Black Panther as an IP isn't something they would want to build on - I mean its clearly a post-agreement IP that has no presence currently in their parks. And thematically, where do they put it? Does Wakanda really scream Epic Universe? I think what's really going on here is that Universal wants out of the agreement, but to save face they can't make the wholesale decision. Give up one IP at a time and then as the Marvel Island rides start to lose their luster, convert the area to Godric's Hollow, including the Avada Kadavra Experience, Nagini's - the Coaster that Bites Back, and Batty Bagshot's Wild Ride.
All of the above is complete BS, just like this rumor. But a hearty congratulations on 13 whole pages!
