It's impossible to guess exactly what has been cut, but if Galaxy's Edge cost approximately $1 billion, we can get a very rough estimate of how much may be cancelled. For instance, $1 billion dollars wouldn't even buy the entire Walt Disney Studios Park in Paris' Massive expansion with Alien Swirling Saucers, a small Star Wars: Galaxy's Edge with one ride, Avengers Campus, and Arendelle: The Kingdom of Frozen. This makes me wonder what is actually being cancelled, and rather just been postponed.
Here's some costs to keep things relevant (Adjusted for Inflation):
- Star Wars : Galaxy's Edge cost $1 Billion to build. This encompassed two completely new ride systems, and lots of themeing, shopping, and dining.
- Ratatouille's Adventure at Walt Disney Studios Park cost almost $200,000 to build. This was a new ride, with new technology, and potentially includes a restaurant. I'd imagine this price is similar to how much EPCOT's version costs.
- Expedition Everest, opened in 2006, cost about $125,000,000 to build, featuring a new ride with heavy theming, and was, at the time, the most expensive roller coaster ever built.
- Radiator Springs Racers cost $200 million to build, featuring a slot car ride system.
- Mission:Space cost roughly $140 million to build.
- Pooh's Hunny Hunt at Tokyo Disneyland cost almost $200 million to build.
- The Twilight Zone Tower of Terror cost roughly $200 million to build.
- The recent expansion of Hong Kong Disneyland, including Mystic Manor, Big Grizzly Runaway Mine Cars, and a couple of Toy Story flat rides is estimated to cost $500 million to build.
