There seems to be a Disney corporate culture right now in which ideas to "reduce reuse recycle" are considered to be extremely valuable. An extreme allergy to what guests would call the generous provision of novel and unique experiences and a strong preference for minimal makeovers and recycling of materials and ideas. Especially if the hand-me-down items can be disguised as something new and at least promising for the future if not actually delivering.
The whole approach is reminiscent of the sales showroom for a condo development which has models and paintings of the fabulous towers, balconies, swimming pools, fitness facilities, and so on. Not an experience but a glitzy simulation of one.
The side-by-side cloning of existing rides is also reminiscent of a condo development where they build the first tower and sell it out, then build 1,2,3 clones of it side by side.
I'm not saying that Disney will never build new, unique and great rides and attractions again. But it's obvious that they're going to delay and prolong their construction as long as they possibly can, and foist off cloned experiences and simulated progress on their guests in the meantime.
If you'll excuse me for beating a dead horse, Universal doesn't shut down attractions and build "blue sky rooms" to pre-sell new rides and lands that won't exist for 5 years or more. They put up fences and start digging.
