I'm not ready to commit to this 100% either way yet myself but for the sake of RUMOR talk I'll throw this out there.
What if Disney and Universal actually did have a meeting and came to an agreement...
And within that agreement Disney is allowed full access to GoTG. Disney can then put Marvel in its East Coast Resort and a much needed IP into Epcot that upper management desperately wants.
Universal is then granted full access to the MCU characters of Marvel and has exclusive rights to MCU Avengers main characters in Florida. Disney also picks up the check for the actors to appear in a Universal Avengers ride as a part of the complete rebuild of Marvel Superhero Island. Finally Universal also has the ability to acquire rights to utilize DC Comic Characters for a third gate if they so choose. (PS Don't get lost on the DC Comics remark, remember were talking rumor agreements and what would benefit each other) Its all just RUMOR talk and nothing more.
The only problem I see with the MCU characters going to Universal and GOTG going to Disney is when Infinity War comes out and features both sets of characters. If people see GOTG advertised at Disney, they will assume that the rest of the characters will be there and vice versa with Universal.
Either way, it's going to get people to Orlando, even if they end up at the wrong park and it's giving the people what they want.
It could also be the start of Universal and Disney building a new relationship .
Does anyone know if DC is something that Universal wants? I know early IOA plans were for DC, but have not heard any interest since.
I do wonder about the Terminator gift shop. They have carried plenty of DC and Doctor Who merchandise. Was this just a financial move or maybe a way to track guest interest in those franchises?
I think it really depends on how the future movies do, it's not been a great start however.
