For those who are interested, looking at the new blueprint picture, here are some of the items they have ordered:
Large Cast Iron Dinner Bell by Cajun Cookware:

Footed Crescent Bracket:

I do not think that this will have anything to do with New Orleans, the Cajun Cookware was just from the brand name.
I was playing Bioshock 2 online last night with my friend and while I don't believe they would make the video game a haunted house, but without knowing anything, who knows. The Little Sisters in the game are in an orphanage and you can choose to rescue them or harvest them. Can't wait til we find out more.
Also, the other picture of the warehouse from the update is for sure going to be a history of HHN type house. It looks like a werewolf type hand, or as mentioned Frankenstein. You can make out a bear to the left of the hand, probably the one from Scary Tales two years ago.
