Good thing that you saved your money. It not only received horrible reviews, but it was literally the worst scareacting experience I have ever had in my ten years of being a haunt actor (not really RZ's fault as it is the main staff of the event.) Seriously, after the first weekend 40% of actors quit, and every weekend after that there were fewer and fewer. I was really surprised it came back this past Halloween, and from what I heard (I did not work this year) it wasn't any better.
But, regarding the theorized lineup
The givens, to me, are Krampus and Purge. Just because... I mean, Krampus is fucking awesome and Purge has a new film coming out this year. Although, I'd personally rather see Purge as a street again I think.
The rest of them, as others have said, wouldn't really be surprising as those are titles/IPs that are always thrown around.
I guess I'd be a little surprised if AHS finally got its house because it was my understanding that it's never been done before because FX/A&D would want to go all out and not hold anything back and make it not necessarily an "extreme house" but one that would require a waiver or an age limit or something. Idk, I thought I remembered someone saying something like that at one point last year... I could be mistaken. It could obviously be altered to just be a typical haunt though and it wouldn't surprise me. AHS needs some life/interest breathed back into it- it's popularity has been waning the past two seasons. A house could respark interest.
If TWD returns, again, I'll be sad but not surprised.
