While I'm sure it's just a prop/effect not put in yet, I am very much hoping to see Dracula's restraints added onto his ring through projection mapping to show him literally breaking free of them, as currently he's just kinda floating there in the locked position, despite nothing holding him there.
Quick edit, and upon rewatching the leaked clip I'm now almost positive it's just something not put in yet, as you can see the holders for his restraints on the ring. The cape effect wasn't there on my Thursday rides, so it seems they're adding more and more onto the projection mapping, cool!
I'm also going back tomorrow, so I'll keep y'all updated on if it's potentially there.
