To those who keep saying Amityville Horror is imminent, you need to realize a few things on the Hollywood side of the business...
The reason we so often see Blumhouse releases represented at HHN (moreso Hollywood than Orlando, admittedly) is because Blumhouse maintains an overall "first-look" deal with Universal for distribution. That puts Purge, Insidious, Ouija, and other prominent Blumhouse franchises in the Universal toy box. (IMPORTANT DISTINCTION: The Conjuring is not Blumhouse, it's Warner Bros. James Wan just happened to direct both.)
Amityville Horror is a Blumhouse release but will NOT be distributed by Universal; it and the franchise belong to the notoriously difficult to work with The Weinstein Company... the very same outfit that controls Scream (both the movie franchise and television series). As we all know, they do not play nice with Universal (or anyone, really). They were already dissatisfied with Scream, so the chances of them signing over their other prominent horror franchise is next to zilch.
That alone should disqualify it from speculation (though the incidental paper craft model will insure YouTubers guaranteeing it for months). There's another wrinkle, though - the new movie is crap. I haven't seen it in full, but I know test screenings were abysmal. I know it's gone through multiple rounds of reshoots. And I know it's had its release date pushed back multiple years. If all goes according to plan, it's finally going to get dumped early next year. (If it gets released at all - rumblings that Weinstein wants to just shelve it and not bother with a P&A push.)
This is not the sign of a release that anyone is enthusiastic about, much less interested in pursuing a synergetic haunt for. So I say with 99% certainty, we will not see Amityville Horror next year, or any time soon. (There's also the matter of Conjuring 2 covering the same ground, but who's counting?)
My guesses, for what they're worth?
-American Horror Story
-Conjuring franchise (collaboration w/ Warner Bros. for Exorcist opened doors)
-Trick r Treat (less likely but could be the A&D favorite "Cabin in the Woods" effort)
-Five Nights at Freddy's (you laugh, but, just watch)
-Insidious: Return to the Further (Chapter 4 comes out next year. Lot of rumblings of its return to Hollywood. The script is solid.)
That'll do it for the IPs unless they drag out Walking Dead one more time. I'm not confident IT will be anywhere near either coast. Murphy/FX may push for Scream Queens if it can manage to draw some numbers as contract renegotiations take place for AHS in future years.
Originals, I couldn't say, but I'd echo sentiments that Vamp '55 seems like the perfect excuse to revive "Hell High."
