I'm not arguing with you. I'm just saying it is possible that Universal can still end up on the short side of this, such that they might consider changes down the road when fiscally prudent and the comic-book-movie fad has ended, and either re-theme the area or switch over to another franchise...unless they got he contract so cheap it can't possibly make sense to do so.
From what I read of the contract..... Universal got the contract for a virtual song. Considering in the mid-90's when the contract was written Marvel's draw wasn't entirely known, Universal essentially took a large risk at the time which has since paid off handsomely.
Essentially, From a $$ standpoint, At this time the only requirements are for Universal to spend a certain percentage of their marketing budget highlighting the Marvel properties as long as a minimum spend is spent. With the billboards around Orlando, and other "resort wide" marketing that includes the Marvel Island, This isn't that hard to do.
They also must dedicate a % of space for marketing of Marvel merchandise. Again, This isn't that hard of a requirement for them to meet, especially with the shops around the Marvel Island meeting a majority of the space requirements.
And then there is the annual Licensing Fee. At this point of the contract, The fee structure is set as a simple reoccurring fee with an annual increase based off a agreed upon inflation index. After the annual fee minimum requirement is met, I believe there may also be a small flat percentage to account for overall park revenue... but with the credits they receive and they way it's written, it wouldn't be any concern either. All the initial fees and lump sum payments required in the contract were met years ago. Since the contract sets the increases to those fees based on the rate of inflation, they are not impacted by the increasing value of the properties themselves. Even better, They get a credit towards those park licensing annual fees on all licensing fees attached to the Marvel Merchandise sold which is sold by the resort.... So let's say that they buy a $5 Marvel Action Figure from Hasbro [or whoever], and Hasbro pays $1 of that wholesale cost back to Marvel to meet their licensing fee requirements, Universal gets credit for the $1 towards their park Licensing fees.
In a way, with the increasing value of the Marvel characters, and toy/Merch contracts being written much different than the park contract, It's more likely that the cost of licensing the properties for toys and trinkets will increase at a higher rate than the fees required by Universal for the Park rights. This will only lead to a win for Universal since people will want more marvel merch because of the movies, which would in turn give them not only the nice profit on the merch sales, but also additional credit towards the required fees to be paid to Marvel for the license.
