Bruno always writes in a large element of surprise regarding the killer in every single episode mystery. With a mystery of the largest scale I just find it hard to believe that he would telegraph who Red John is to us even if he says one of seven or six or five. He is too good a writer to take the element of surprise out and prove it's one of the five left.

His where's Waldo comment keeps ringing in my head. A "where's Waldo scenario" is not ... it's down to five people! Who among them is Red John!

To me it is obvious that it is not someone on the list because too many people no matter who of the seven would say "oh yeah that's what I thought" Bruno is better than that. I don't know who but they are not on the list.
