Thunderbolt was opened last week, so I think you are going to find experience on the track at a bare minimum. (and last week was an open house doing parade laps I believe)
The owners were at the SVTOA dinner talking about it. Being a built-from-scratch track, there isn't much in elevation changes. I can't remember much details about the turns. They did have a short video of it while under construction. I'll see if I can find if that was ever posted online.
