SWL aside (I'm not going to give them credit, or denigrate them, for something that's not even built yet), WDI's track record over the last 20 years is terrible. Absolutely terrible. Future World has completely fallen apart, World Showcase has been used as an excuse to cram IP anywhere they can, DCA was a disaster, Animal Kingdom is a 1/4 day park, Pandora was dated on the day it opened, MGM Studios is a shell of its former self (GMR gone, Backlot Tour gone, functional studio concept abandoned), water features removed pretty much all over the WDW resort, Alien Encounter replaced by Stitch, screwed up the Tiki Room for a decade with Stitch (finally fixed, thankfully), removal of Country Bears and Mr. Toad to cram Pooh into the parks, interactive queues that everyone with a brain knows would break down and never be repaired, DL Peoplemover debacle, DL Tomorrowland redo debacle (including moving the Astro Jets to the hub), Pleasure Island removal, turning Pirates into the Jack Sparrow version of Where's Waldo, Yeti broken immediately and never fixed ...
WDI's track record is not good, going on two decades now.
EDIT: Put another way, what's the last thing WDI was responsible for domestically, that on the day it opened, everyone said, "Wow, that's so much better than I expected!" Cars Land? Maybe, but they had to remove Luigi's Flying Tires two years later. World of Color? Maybe. Remember Dreams Come True Fireworks? Definitely (I don't even know ... is WDI responsible for developing the fireworks shows?). Fantasmic? That was 1998. Temple of the Forbidden Eye? 1995. Soarin is probably the answer but that was 17-18 years ago.
