^Meh, by themselves no one would care about those titles, but perhaps they will simply bill it as "World's Most Extreme Spinning Coaster' and have those as subpoints.
I think the "Mountain Mystery" tidbit is really interesting. Certainly more fuel for the "Mountain" theme rumor. In any case it is certainly a parallel with Dollywood's Mystery Mine project. There was a massive rumor about ten years ago that they were working on their own version, but it was scrapped at the last minute due to budget cuts, the recession, and issues with Mystery Mine. Perhaps there are certain things from that project that are being transferred to this one? Theming concepts maybe?
