I go by this park daily and it hasn't done a single test run, plus I think it would be dumb to open it up so late in the season. 2018 is my guess at this point.
I don't like the fact that the restraints don't have retaining straps, and that they are only fixed on one side.
Having ridden the one at Movie Park Germany the bucket seats make the restarints feel fine. In any case they're there to stop children from getting out the ride as opposed to restraining you from ejector airtime.
Just drove past the park, saw it testing with my own eyes. Looks cool. Not sure why they're testing now as I think it's unlikely we see this open for Christmas. Guess they've got to start sometime.
