There was some pretty hefty suggestions from inside that it was going to be the Automatic Guided All-Terrain Vehicle ride system. It is unclear when that was abandoned, or even how serious that project direction was.I am actually shocked there isn't more tears here about no trackless. The way so many had convinced themselves it would be... counter to all rational thought. The pivot to 'the ride will be canceled' as a coping mechanism wasn't what I expected the jump to be.
The need for input makes me wonder if instead of RSR, we get a more lightweight, hybrid version of EMV+Test Track.. where the ride vehicle augments the movement vs just driving over the rough terrain. They vehicles won't be able to drive over such offroad features like that with traditional ATV kinda suspension like they experienced in their field testing. They will have to mimic it with actuators like the EMVs do.
For those crying "I don't need another XYZ..." - I think Disney is smart enough here they can't just rebrand RSR. And the kind of stuff they are highlighting in their video would be pointless for a RSR/TestTrack equivalent too. They clearly want to add a different dynamic to the experience. If they can do the EMV thing, but in the smaller form factor it could be interesting.
I agree that whatever its built has to differ from Test Track and RSR. I'm disappointed that we may not get the trackless, as that would have really been something groundbreaking. I'm also not convinced that off-road rallying =< speed.
It will be interesting to see exactly what is built, and how much show is brought to this experience beyond the ride system.
