Stab in the dark:
Purged: Whatever the late house is. Seems pretty easy, but we also have no idea what the replacement is.
Returning: Evil Dead. It was at the event in 2013.
Exclusivity: The 5th/6th IP. It's known we have something Hollywood doesn't. Perhaps it's The Mummy?
Misnomer:
The Conjuring. It has to fit in somewhere on the list.
Crossover: Catacombs/Gothic. If that's what you've been alluding to with the tent
Bloody: A vampire house?
Plain: Scarecrow icon house? Scarecrows are in fields and plains.
