Disney is not addressing a single one of the areas in need of redevelopment in the WDW parks. Tomorrowland, Imagination, and Animation Courtyard will all continue to be underutilized spaces at best and blights at worst. Meanwhile, perfectly functional, often excellent elements of the parks are being ripped out for underwhelming replacements.
Improving the parks is not Disney’s primary goal. A large contributing factor to this is the fact that the tremendously irritating reservations systems WDW has put in place have created a perverse incentive structure.
