So they can update the whole park, but Marvel Super Hero Island just sits there with nothing new forever? Not the best use of that real estate, really, but if it keeps Disney at bay I guess it's a strategy.
Universal can still add, but not subtract without a replacement. For instance, Universal upgraded Spiderman without any adverse affect on their agreement.
I would think it is mostly lack of usage that will cause the rights to revert back to Disney. If Universal wants to continue to maintain the franchise, it should continue to look towards expanding the attractions slate. However, what will happen if they decide to remove Spiderman? Probably nothing because the Hulk roller coaster is still there.
Look at the Marvel movie agreements. Sony continue to reboot Spiderman to maintain a lock on the franchise.
I haven't been able to make the trip to Orlando this year so next year I feel it will be very much all about UO.
Consistent capacity crowds would definitely change the whole vacation experience.. the only saving grace will be early entry.
