So first off, based on the titles of the upcoming episodes as well as the info given by Mahoney in Tvguide interview, I believe Red John is one part of a 3-headed "Dragon" including possibly Partridge in some position with Haffner as Red John and Stiles as head and leader of the beast, and possibly the Tyger organization. All of the clues when held with common sense point to Haffner as Red John, but they also point to something more, something bigger. I have no clue what role Partridge has to play in it, but Heller says he died early for a reason-suspicious.
I also think it is quite clear that what was heard as acrophobia-fear of heights, is actually arachnophobia-see Haffner. Haffner seems to be the man doing the killings now with the voice telling Patrick that "Theresa" can't come to the phone.0, as well as Haffners silhouette at the door in tonight's episode. Yet, so much is still to be revealed like WHAT EXACTLY AND WHY EXACTLY DID PARTRIDGE have to die first? That is all....
