I would absolutely be down for a Vanity Ball house, there's a lot of potential there. (Plus another fab soundtrack!)
I too, am lamenting what seems like no Resident Evil on the map...but I also can't help but notice it seems like there's no more Heavy Metal Hell on the map either. Which makes the Dance Macabre clue all the more intriguing, since Heavy Metal Hell wouldn't be used if we have a GHOST house which would fulfill the metal theme in spades. Plus, I can absolutely see how rumors initially led to Heavy Metal Hell...when it could actually be a GHOST house. Metal and Hell are absolutely that bands M.O.
I am also quite happy still seeing the Pins a la' Hellraiser!
As for the burning book, Evil Dead Burn?
Finally, the paw print. I am genuinely hoping that is Canine/Lupine and not feline. Because unless they have a truly killer concept for it...a house of Cat Lady on Crooked Lane would be a total waste just a year after we experienced the all-timer of a zone. I want themes I haven't seen in a while, not stuff that's still fresh in my memory from last year.
