:shock: Bravo Gardaland! We need more marketing departments like yours!
Could it have been a possibility that at the time B&M was not quite certain about a third inversion and it was later okayed? That way the ride did not overpromise (kinda like Maverick :?) I believe this is how the Voyage at Holiday World got one of it's three 90 degree banked turns. Yeah I know wood is not the same as steel, but it's the same concept though.
EDIT: Just reread the statement on newsplussnotes.com and it states that the ride will have two zero-g rolls. Before this inversion was put in there was only 1 zero-g roll, the other inversion is a heartline roll. Therefore, this this leads me to believe that the heartline roll might have been a late addition, and could possibility be "Mavericked" if problems arise with it.
