Since that account suddenly seems a bit more credible (assuming you find the speculation map credible), probably worth discussing the other scoops dropped. My comments in italics:
* Bugs a "1950s giant insect" house -- sounds like a lock to be this year's dark comedy house
* Underground creatures = mutants on a subway -- not a Terror Mines reimagining like I had hoped but has potential
* Wolfman v. Mummy includes Dracula -- possibly a London-set house? Mummy escapes museum to meet the local monsters?
* Zones all themed to traditional Halloween; in addition to Scarecrow redux, mutated trick-or-treaters in NYC and a witch zone
This is the same event that did Evil Dead and its pastiche Cabin in the Woods in the same year on the same street.
