I think we can safely say it's not Partridge, unless it was another clever trick.

   I Think Red John will be revealed probably to be Brett Partridge :
          Reasons are:
Heller's assessment of Brett partridge:

Brett Partridge (Jack Plotnick): "You've always got to be suspicious of the nerds," Heller cautions. "He's both a slightly embittered soul and a very intelligent person. Someone who feels they've been underestimated, underrated and mistreated by the world. Demographically, he's right there where a profiler would say, 'Yeah.'" As far as his career choice as a forensic investigator, "That's exactly the kind of job that a serial killer would want to take up. That's exactly the interests that a serial killer would have. [But] he always appears slightly weedy. Is he concealing strength or is he really that flaccid a person? It's hard to tell."

         Brett Stiles is maybe related to Brett Partridge in some way, which not only explains his Red John's connection to Visualize, but also explains why there are so many important people involved in covering up Red John's Trail.

         Bob Kirkland is secretly connected to both Red John and Brett Stiles through Visualize. Bob Kirkland also masterminded what will be eventually revealed to be the phony death of Lorelei Martins, and the information he collected on Jane is what allowed Red John to produce the tape that seemed to suggest a psychic prediction of Jane's suspect list prior to her death, when in fact that tape was made more recently.

        I accept the idea that "Brett Partridge is Red John",if Bruno Heller tells us the true side         of Partridge, I mean the mysterious side: intelligence, management and influence on           people.
       

I think The Mentalist is too good of a show to not have a twist to the RJ storyline so I don't think they are just going to come out and say whoever Red John is. There are many good theories and clues for each suspect that could also be "red herrings" so I'm not particularly sure who he is but this picture of RJ killing looks alot like  Brett Partridge.

Some people say Brett Partridge is so young to be the RJ, but the actor Jack Plotnick have 44 years old, so I think he is Red John!

I just want to say that human nature has been given this amazing ability to be in denial.

---- DEXTER SPOILERS ----
I want to go back to dexter's final, since the start of the season, pictures revealing debra
morgan's death has been published, but some decided that dexter only fake her death.
furthermore, everyone guessed that oliver saxon was tbs, but there were some who
claimed crazy theories, like vogel is the tbs, or even debra!
And ofcouse who the tbs was? oliver saxon, did debra morgan die? yes she did.
---- DEXTER SPOILERS ----

People keep suspect people that aren't even on the 7-list (or even these that say pj is rj),
which is absurd.
And the people that think rj can be other than brett partridge, which can't even happen!

1) http://www.youtube.com/watch?v=OcFcQv8bVmA this is the sound of brett partridge, no
one else can that like that, this is and can only be brett partridge as red john @ 00:23
2) Rosalind Harker's theory is honest and trustable, bruno heller uses her knowledge since
season 1, and patrick jane always knew she was honest.
the only people that can even be red john, based on his visual profile are brett stiles (which
isnt rj because of his old age), bob kirkland (that has been proven many times that he cant
be rj, and the only one left that match the voice of rj, the profile of rj, and the main suspect
for rj is and always will be: brett partridge.

you can actually hear his freaking voice, keep being in denial.
RED JOHN = BRETT PARTRIDGE, dont let bruno heller fool you.
crazy conspiracy rarely happen, there's more than enough information to determine
rj's identity.

same as dexter, i hope that site owner won't take this site down on 22/11/13 so we, the
people who knows it's brett partridge, can say "we told you so :)".
And we will.. (rj will be revealed at episode 8 "Red John").

 I think that none of those on the list are actual suspects but rather a game. If you remember Jane put a toothpick in the door and when he returned he found it on the floor. When he picked it up he had somewhat of a half smile on his face, like someone was suppose to break in and see his board. Knowing someone would come he created a fake list that red john fell for, I mean we haven't seen what happened after he broke that dvd. The way the show has gone in the past this seems like a plausible theory to me. However I have heard the creator or someone said that red john IS in fact on the list, so it isn't likely unless he lied which maybe, but I think this would have been a good clever way to catch him maybe
anyway

I can eliminate one of the suspects in the list based on previous information, the visualize lead. Red john was someone in his late teens or 20s on that farm 25 years ago making him 45ish-55 years of age. Bret Stiles is too old, the actor that plays him is 70.

Kirkland is an obvious choice the way he is so creepy, but I feel like he is more of an accomplice.

Of those on the list the only ones that seems plausible to me are Haffner and Partridge
Both seem obvious though, we are somewhat lead to believe that Haffner was on that farm which could make him the killer obviously. Partridge's voice sound so much like the times we have heard red john's voice which again makes him obvious then.

If the list is real I'd go with partridge, but honestly he is kind of a random character, and if he is RJ that is a moderately lame ending. Any of them being red john......I like my idea better

I think, for the reasons we all know, like his voice and another, which is RJ Partridge.

I wanted to add one thing, regard the written He is Mar, might actually be the address of RJ?
"Mar" could stand for Marin County or Sacramento Marina.
"He" might actually be the numbers 11 and 9 (written a little 'bad), "is" the number 15, then 11915?
