I thought it was already confirmed to have a chain or cable? I don't want to know what happens in the tunnel, want it to be a surprise, and I hope to God that there is no show or something, I hope it goes in, stops at the switchtrack, goes backwards and finishes. Although I like the idea of a fake station for the switchtrack, so you think it's over then you suddenly go backwards.
But if there is a pre-show or mid-ride-show, then that will be silly, if they want a story, play it in the queue like Oblivion with videos or how they did with Nemesis, over the speakers, or just with signs you read in the queue.
