I do want to do this as I've been wanting to settle and do a Spec post more properly--here are a few thoughts I have. This is more in general and does include what I think might be the IPs--but this is pure rambling with deduction. And to keep it safe--limiting myself to three thoughts.
Ghostbusters = So I talked about this before on the HHN33 thread, and I will actually be bringing it up here. Ghostbusters is hitting the 40th Anniversary of the IP with the 2024 release of Frozen Empire. Ghostbusters is while not as large, still large enough to be a notable addition for the sake of merchandising and brand recognition. The franchise is climbing back up with the success of Afterlife--and it would make sense given the seemingly positive relationship with UDX and Sony Pictures; that Ghostbusters is properly featured here.
If not here--then I would think of someplace else...for another discussion.
The Weeknd = Since 2021, John Murdy and Abel Tesfaye have been more promimently and actively working together with that of After Hours Nightmare. And from what has been clear, it has been a relationship that has allowed Singapore to be able to work with The Weeknd's Abel Tesfaye, with John Murdy helping in the initial discussions before Singapore took it to shape as they can.
2024 is seemingly going to be the last "Major" year of The Weeknd as a character for Abel. The final album is well into production as of September, Abel has multiple tours lined up for Oceania, Asia, the Middle East, and Africa. But ontop of that; Abel's producers have already hinted and gleaned that Abel is working on a North American 2024 Tour.
Additionally, outside of that--post production should be in full spring for the Schults directed film; which is rumored to have major connections to the album--and rumors of a horror tone with The Weeknd losing his voice in the film; and seemingly being kidnapped.
I genuinely think outside of FNAF (which has already been talked about more); The Weeknd is probably one of the few larger IP's that I genuinely think is absolutely coming into play for 2024. This comes with a tinge of bias, but this also comes with acknowledgement on how much is seemingly on the docket.
Paramount = So, why Paramount? This is a wider topic that I think owes a larger discussion, as we simply do not know the full means of what it can imply; but if you look at what UC is developing on for Universal Kids Frisco, it seems Paramount is back and has fully opened their doors to that of the parks to work with them.
Granted--we've had the connotation and thought that in the past things have been restrictive, but perhaps now with them working with Universal on being what seems to be a headliner for Frisco; that things could change in allowing them to also work with Universal for the sake of specialty events like HHN.
A Quiet Place and Friday The 13th come to mind immediately; due to both A Quiet Place: Day One and the respective Peacock/A24 series of Crystal Lake aiming to seemingly hit the service of Peacock in 2024. Both have core horror elements that could work well in it's favor; despite the scale differences of both. They've also been going at it over the course of the past 8 years; of having a core Slasher type experience present at HHN Hollywood, to where I wonder if Murdy might go at it for the Hockeyman (or for Texas due to the 50th from that).

Sorry for being wordy and wanting to post a long-post, but these three have been nagging my thoughts for a bit and I wanted to get it out.
