Yes, It costs Disney nothing, but the cheapest, bare bones overlay or even just a Star Wars weekends or Frozen Summer Fun type deal would end up making them more money. Not only would Disney making money on exclusive Marvel merchandise, food, and beverages, but it brings in a whole new group of paying customers to come to their park where they could possibly buy other merchandise, food, and beverages. If DHS were to have something like this, it would only increase the likelihood of these people staying at one of their resorts so they can visit the other 3 parks where they can buy even more merchandise, food, and beverages. Its not just about the Marvel profit, but the overall profit. So while I'm sure Disney is fine with mooching off Universal with the deal as is, they certainly don't want to create a situation in which Universal takes the overall profit and attendance away from them. From what I've heard, Disney has taken the buzz about Potter to heart when it comes to making SWL. So much so that they even got one of the designers on Potter to lead it. Like you, I know that corporations aren't black and white and can always work together. The hypothetical situation we speak of here, however, seems highly unlikely since it would ultimately end up detracting from Disney's overall product in a much bigger way than Potter did. I also think that it would be just as unlikely that re-negotiations that would work in Disney's favor since it would detract from Universal's overall product in big way. This is the reason why I'm going against these theories and believe that the contract will remain unchanged.
