My assumption is The Keeper is going to be the horror host for a best of maze as they kept saying he was part of an “attraction” and that they wanted to make something harkening back to past mazes, without it feeling jumbled.
Logically using The Keeper as a host means they could keep the maze around for a few years too since it will have a general storyline that doesn’t translate to JUST an anniversary year.
Given that Ken Parks also referred to having The Green Witch headlining a house, show, and being on a ride, I could also see The Keeper being the host of the rumored anniversary show in the Walter Knott Theater too.
