I don't want to shut the idea out 100% that the trains don't slinky, but from what i've seen people who I tend to trust say while following this project, it's going to act as a pretty standard coaster car.
If it makes you feel any better, all the rockwork and the Woody's roundup area that was cut saved nearly $400M on this project. It was going to be an absurd $500M project, now it's not even touching $100M I believe.
While those extra touches would've been nice, it would've sorta been like putting lipstick on a pig. A turd isn't going to stop being a turd because you dressed it up.
Probably figured they can save $400 million and without the rockwork it would make it easier to tear out in 5-10 years to build more Star Wars.
