I think the part of the contract you're referring to just means Disney can't brand the "under used" (by Comcast/Universal) properties like GotG as Marvel attractions which also applies to the west coast. That's why it's not called "Marvel's Guardians of the Galaxy Mission: BREAKOUT". The difference is that on the east coast, Disney isn't allowed to use Avengers, F4, X-men, and Spider-man families.
That's the part about outside of the east coast. The part I'm referring to clearly states that rides involving the marvel characters even not included in universals area are prohibited within 60 miles of IOA. The verbiage is such that Disney could try to remove the marvel branding, but Universal would probably challenge it and would most certainly win. Guardians are a marvel property whether they brand it as such or not, so it falls into that 60 mile rule.
Restrictions as to the geographic location of The Marvel Action Universe in areas where MCA has exclusive rights hereunder.
a. The Marvel Action Universe will not be within 60 miles of any Universal Theme Park with a THE MARVEL UNIVERSE
b. Mini-theme parks, recreation centers, game centers and the like designated with the Marvel name or the name of any Marvel characters or any major entertainment component of a Marvel Action Universe such as a motion based film ride shall not be within 60 miles of any Universal Theme Park with a THE MARVEL UNIVERSE.
The key words there being "designated with the marvel name
or the name of
any Marvel characters or any major component of the Marvel Action Universe"
Disney lost the right to use Guardians as soon as the first movie became a hit. It's now a major property, and therefore not usable for WDW.
Like I said before, rumors are rumors. There has been a rumored Jurassic park renovation for the last 10 or so years at IOA, never has happened or shown signs of happening. Disney cannot legally build a guardians of the galaxy themed attraction unless the move Epcot 60 miles away from IOA
