My speculation
confirmed:
Saw, Living Nightmare, Platform 15, Containment
speculation for other 6 attractions;
1. Blair Witch(basically confirmed)
2. Sanctum( relocation or different walking dead maze)
3. Walking Dead The Ride comes Alive
4. Zombie Hunt reopens
5. Roaming Actors/ Scare Zone
6. Cinema Show
I hope I'm wrong but I don’t think we will see more than 2 new mazes. I think the majority of them will be experiences or ‘encounters’ as they describe it.
