So with the new speculated lineup, I'd be totally fine with this house list if it's all confirmed true. (As usual, nothing is confirmed until Uni says so.)
I can see how
@Ringwraith has mentioned the lineup has a indie horror festival/home-made kind of vibe, and each of the IP's and originals definitely have their own unique potentials.
Regarding TCM 3D, I'm honestly not opposed to this. Is the film a trainwreck? Yes! But that doesn't mean the house itself is gonna' be bad, after all there's been good films/shows that had lackluster houses. It really comes to overall execution, and TCM 3D does provide a nice amount of settings and unique kills to play with. An if you wanna' bring continuity into the equation, TCM 3D is taken as a direct sequel to the original film...which was the last TCM house Orlando has done. All in all, I can see this being a nice Dark Horse/Sleeper if it's done well. (Now with SotL being the house they didn't get, while it would've been interesting to see how they do that film as a house, personally it's a IP that's not really high on my list to see as a house.)
As for HHN Icons, I'm intrigued to see what angle they would go with it. Are they gonna' try to incorporate some more past house references from whatever respective years for each Icon they feature? Or will they go in a really original route with creating fitting scenes for a Icon to play in?
Finally, for Mannequin/Puppet Theater, considering Mannequin's are one of the few things which can truly creep me out when done right...there is really no other house that I'll be highly anticipating and downright DREADING to see. Seriously, this is a giant YES/NOPE for me.
