Mission: Space will debut the next version of Fastpass. The new version involves a computer that determines what the ride's current capacity is (if people w/ wheelchairs try to get on, it obviously temporarily drops the capacity) and determines how many fastpasses to give out during each five minute interval. The purpose is to make it so fastpass lines are shorter. Mission: Space will be the first disney attraction designed for Fastpass, which, to me, means it will have two completely different queues. If Primeval Whirl is popular, it would also be prime for the second version of Fastpass, as they could have one coaster entirely set aside for Fastpass, and have the new version figure out its capacity at any moment.
