One of the issues is that Disney doesn't view having the parks as global draws to be important. (Having people visit all the parks isn't a priority to them). So they don't see the need to have DLP be super differentiated, and thus they're okay with Studios being a mish mash of little random things for marketing purposes. I also think that they don't see Efteling and Europa Park as competition, so they don't feel the need to improve the resort overall (hence why you have nothing new at the castle park in 20 years). Hopefully Universal in the UK does well and that can lead to longer term investment in DLP (years too late but better than nothing).
