There won't be a whole lot of room for fast coaster segments, though. Remember, this will be indoors.
They can't make another main ride that is highly restrictive. Doing that will be a failure. This is the ride for the expansion. Yes the train is there, but we don't know what the deal with that is yet. They need this ride to be available and appealing to more people than FJ was. It will be a thrill ride. But it's not going to be a super thrill.
And if you call a hugely detailed, mildly thrilling, state of the art ride that "makes Forbidden Journey look like It's a Small World" (actual quote from an insider)...well, I dunno what to say.
