Catacombs/Gothic crossover is definitely in a soundstage, Evil Dead is most likely either in a soundstage or sprung tent, Scarecrow maze is probably Parade building, Blumhouse Mashup is probably going in a soundstage or Sprung Tent, and Saw is probably going in Shrek queue.
My Predictions:
AHS: SS 21
The Shining: SS 22
Bayou of Blood: SS?
Blumhouse Mashup: Sprung Tent
Saw: Shrek
Evil Dead: Sprung Tent
Scarecrow: Parade Building
Gothic/Catacombs: SS?
Dark Fortunes/9th Maze: MIB Tent
