The robot claw ride is actually based on a ride of Huss called "
Jump²". It was also included in RCT3.
The ride you call SoundMachine is called
Star Shape from the ride manufacturer Zierer.
However, I'm not sure if rides you see from early stages as the trailer or first 3d-modelling will be there. Some rides might only have been there for the trailer and could have been eliminated in the development to make place for other rides.
I still hope that they will come up with a good, normal top spin with a very good rideprogram (still hoping for the
Suspended version, but the classic one with floor seems more popular unfortunately).
Speaking of rideprograms, I hope that PlanetCoaster could give more info about the rideprograms/animations for the flatrides. It would be ver awesome if you would have a choice between several rideprograms for different flatrides, or beter, create an own rideprogram. Especially for rides like TopSpins or that Jump² ride.
