Small thought (As I have done on other places), since HHN20, the year following the anniversary year then followed that of an icon, one to begin the cycle again and go forward. 2011 was Lady Luck, who didn't get that much in presence outside of promotional and scarezone, and then 2016 gave Chance, who got a maze but had mishandled marketing.
But thanks to the delay, assuming if they are going to continue the narrative of original aspects, there is an icon that could come very easily into play that could explain the more IP-heavy lineup. And that in turn comes down to the character of Julian Browning, otherwise known as The Usher. Why do I bring him up? Well--The Universal Palace Theater, for this year in chronological terms, is 100 years old. Let's assume the Icon aspect comes back into play for HHN31..and if Usher comes in, how do you do that?
Simple. Reinvigorate with a "Grand reopening" of the Universal Palace Theater. Have it be a celebration of horror of various forms, and all the while a Phantom-Julian lurks around, wanting to maintain his movie theater to be following the rules he made bare. Feels very easy to do, feels like a way to allow all the IP's potentially being represented for Orlando to get it's day in court, and you could even use "Never go Alone" in the marketing, as part of the movie theater's reopening.
