The problem with Sorcerer's is they never expanded to TL or NFL. So everyone is in four parts of the park only.
This is something I do not understand with Disney. They have something but every year or two they could easily come up with a new story... Have it an entry project for new Imagineers.
I had been saying this about Mission Space for years... There is nothing wrong with the attraction in terms of the equipment, but a video is easier to refresh than tearing down and rebuilding a whole attraction.
