Random thoughts:
1) Predicting originals is a fools game, but I wouldn't be surprised by a Major Sweets related house - a twisted take on Willy Wonka (which is already pretty twisted) seems to offer a lot of potential they haven't explored. Would slot neatly as the humor house.
2) We won't get an icon on the level of the classics but we'll get some mini-icons like Boo and the Pumpkin Lord - they move merch
3) A music house is likely, but it won't be The Weeknd again - diminishing returns, and I don't think either HHN or The Weeknd want to be inextricably linked. Were bridges burned with Eilish? Whoever it is, they have to have Superbowl-level crossover appeal.
4) Regarding IPs, Five Nights seems a natural. If Blumhouse's Exorcist comes out, that might get a house, but no Exorcist otherwise. Chucky fills the slasher spot, so Friday and Freddy and the like are out. He also probably fills the puppet spot, so something like Gremlins is probably also out. Despite the difficulties this year, Evil Dead Rise and Salem's Lot both seem likely candidates. At some point, one suspects that the nostalgia-driven creatives will get to Lost Boys, but I feel like it won't be in 2023 (Salem's Lot feels more likely).
5) Monsters, of course, with a focus on either Creature or Phantom. I feel like Phantom has an edge because creating a believable Jungle environment would be immensely difficult and the obvious alternative, a jungle temple, feels too similar to this year's Mummy.
6) Slaughter Sinema 2? Please? Eh, probably not.
Complete guess line-up: Chucky, Blumhouse's Five Nights (if it comes out in Fall 2023) OR Blumhouse's Exorcist (if Five Nights doesn't), Salem's Lot, Phantom of the Opera, Eilish, Major Sweets, 4 more originals
