I posted this the other day: http://www.whoisredjohn.com/See-a-theory-Red-John/8313

Not trying to re-post theories, but the previous post was before the TV Guide article came out. In summary, back in May, Robin Tunney said she was NOT surprised that Bertram or Stiles were on the list, but was surprised that McAllister and Partridge were.  Then recently she said she was surprised by who RJ was and would've been also had she been that actor.  To me, that removes Bertram and Stiles from the suspect pool.
