Just speculation thoughts...
I think the IP in question missing from the speculation map could be based on a "classic" movie. None of the IPs on the speculation map for Orlando fit the range of feeling "classic" where you walk through a singular film. It seems like every year there is that one "classic" IP that has yet to be properly featured at the event in a house that the creative team is excited to bring to the event. Past examples of what I guess I am talking about include The Exorcist, The Shining, Poltergeist, Ghostbusters, and Beetlejuice.
