Well if somehow this theory is true and Disney has the rights to use any Marvel character post 1994 that wasn't an official Avengers, X-Men, or FF member, or in the Spiderman family then this has the makings for a pretty awesome Marvel Superhero land (if done correctly). With Marvel clearly trying to expand its cinematic universe by adding characters that aren't in the core 4 (Iron Man, Cap, Thor, Hulk), it could open up a ton of opportunities for WDW to get in on Marvel. This would be great branding for DL and WDW to be able to provide different Marvel experiences on each coast, having the original Avengers on the West, and newer Avengers on the east with only GOTG being used in both (but with different ride experiences).
This is all speculative, but after reading the contract numerous times its a logical debatable flaw that the contract has that Disney can use in their favor.
