That will be the truth if they can't get FJ running at full speed, and we end up having another HRRR on our hands
I can only imagine how many problems they're running into with this complex ride system, the large amount of vehicles, plus all of the coordination that has to occur along with the whole thing (like the carousels). As innovative as they were at the time, the carousels were the most common point of failure in Epcot's original Imagination ride.
