This certainly explains why only the Guardians have showed up in WDW so far.
However, there is this clause on the time limit for "complete" ownership of the rights in question:
Within 2 years after opening of THE MARVEL UNIVERSE in Orlando, MCA may retain its worldwide exclusivity for up to 5 additional years by designating another location where it intends to develop THE MARVEL UNIVERSE as part of a theme park, and by paying an option fee of $*** per year. Provided such second theme park opens within such 5 year period, MCA shall maintain worldwide exclusivity for an additional two year period after such opening, and thereafter its rights will be subject to the “shrinkage” or “expansion” concept described above (in the manner described below). |
(As stated at the end of the contract, it was written up in 1994.)
The "shrinkage"/"expansion" clause, of course, refers to the Fantastic Four and Avengers characters. However, the contract goes on to emphasize that this protection is maintained by the option fee.
I would imagine that, at some point, Disney--which now owns Marvel--will make a "co-ownership" deal with Universal similar to its deal with Sony regarding the Spiderman characters.
But regardless, this issue does underline why the 5th Gate can't have a Marvel theme. Again, were such a deal to be made, it'll probably point towards expansions of DHS and an update for the Life/Body pavilion in Epcot--and neither has been mentioned in any reports as of now. Thus, both our general points stand.
