I don't think Candyman is coming, given that
@Legacy said he didn't expect any slashers and Candyman was on the list of slasher movies he posted. If I were to guess, the properties that he's alluding to that aren't "timing" IPs are things like Beetlejuice and Creepshow. I would think Haunting of Hill House/Bly Manor WOULD be a timing IP given that the new season drops this year. Conjuring wouldn't have to be a timing IP even though the 3rd iteration releases on the day HHN opens - because Conjuring is a big enough property to where it could still come next year.
Halloween films, Scream, Friday the 13th, Nightmare on Elm Street, Texas Chainsaw Massacre, Candyman, Psycho, I Know What You Did Last Summer, and Chucky would all appear to me OUT given the slasher info. Other big IPs like Conjuring (including Annabelle & The Nun), The Thing, Hellraiser, IT, Amityville Horror, all Romero, Suspiria, The Exorcist, Gremlins, all UCM, Drag Me To Hell, The Ring, The Omen, Alien(s), and Pumpkinhead would all likely be potentials under the "not slasher" umbrella (I'm not saying ANY of these are coming, just that they wouldn't be ruled out for being "slashers").
