I've always imagined Blumhouse being the last announcement. Considering how fans can be quick to jump to conclusions or complain about a certain choice, especially how a lot were borderline tantrum-throwing when they found out Asylum and Coven were not coming this year. I feel that John would want to take as much time to explain the concept of the Blumhouse maze, like why they're doing it, why certain movies were chosen for it and others weren't, and how some of the chosen movies could incorporate elements to scare guests in a live attraction.
