1. Red John is someone from the list. Saying otherwise is bullshit.

2. If Bruno Heller wanted us to see Red John from the promo, he would have done so. Even though we can identify the man in the promo as McAllister, that doesn't mean he is Red John. Heller would not be that stupid to show Red John in the promo.

3. I believe that the Kirkland story will continue. It's weird to mention the twin brother of Bob Kirkland, Michael, without developing the story. I believe that Reede Smith killed Michael and Bob is still alive or I don't know, but the Kirkland story can't be finished just like that.

4. I am not accusing anybody yet, The Mentalist has proved to be full of twists and turns and we could expect anything from everyone. Bruno Heller did one hell of a job keeping Red John's identity secret.

Those are just my thoughts, I can't wait for next Sunday!
And I hope that this website will not be closed after the reveal of Red John, it would be a shame to lose so many interesting theories that have been posted.
Cheers!
