Quick update: I've heard the same information from two sources now (although they could be getting it from the same source, so YMMV). SDMT exited test-and-adjust just in time for the media preview. They're now having to train multiple shifts of cast members on operations and safety procedures. Evac is a bit of a challenge due to swinging nature of cars. There's a fix for that, but it requires some extra training. As soon as they feel training is sufficient, they'll start putting the ride into regular operation mode. Of course, it will help having some actual riders for the roller coaster, so at that point Cast Member and AP previews may be scheduled. One source said they don't know if this will happen until the last week before May 28th (ie, during the 24 hour day for APs), the other source was a tad bit more optimistic. The end result is the same, training is ongoing. No official word on CM or AP previews, let alone soft openings.
