Just an observation, think about how many roller coasters opened in WDW during its first 30 years. 4; Space Mountain (1975), Big Thunder Mountain (1980), The Barnstormer (1996) and Rock 'n Roller Coaster (1999).
Now think about how many will have opened in the last 10 years 4; Seven Dwarfs Mine Train (2014), Slinky Dog Dash (2018), Cosmic Rewind (2022), TRON (2022/2023).
It's interesting how Disney is increasingly relying on coasters for new rides, instead of inventing their own thrill system (Star Tours, Test Track, Indiana Jones, Tower of Terror, Mission: Space, Soarin') or building long-form multimedia attractions.
