I have a feeling that the animatronics in Carsland will be amazing. I agree with you, as good as these are, Carsland has to be great!
Luigi's Flying Tires is a WDI recreation of the old Flying Saucer Ride that used to be in Disneyland.
As for Mater's Junkyard Jamboree, I'm not too sure. Its the "Same" ride system as the Zamperla's Demolition Derby
(which is the same as Lady Bug Boogie
in Bugs Land) just on a much bigger scale and it does a few different things (swings out like a whip ride) So it could be either really, it looks like a collaboration with Disney building a better ride off an existing ride technology.
