Bertram, McAllister and Shawn Barrlow - none of them is Red John. I know that someone almost bald is shown in promo, and it can be one of them (McAllister can be alive since he was standing next to Bertram and Reede and they weren't hurt, DNA tests can be fake), but they are not Red John. 

Rosalind said that RJ had straight hair, and three man mentioned above are bald with no ability to grow hair again. + Sophie said RJ is middle aged and at least McAllister, but in my opinion also Barlow do not fit this descriptions. 

Kirkland is dead and there are no doubts to it. 

Reede is apparently not RJ, we know for sure after The Red Dragon episode.

Stiles does not match the RJ profile at ALL and i never suspected him.

For a little while I thought Partridge can be RJ, because his voice was quite matching, and Cho didn't check face of the body at morgue in 6x07, but then i figured that:

- RJ is too smart not to modify his voice
- we heard his voice few seasons ago, so Jane would recognize his voice a long time ago
- Patridge looks too young to me
- he seems to be dead

After all that said I have no idea who RJ is. The only options left are:

- it's no one from the list (Yes, I know what Heller said but he can be messing with us)
- it's Micheal Kirkland but that seems soooo illogical and cheap and stupid ending, i would be VERY dissappointed with an ending like that

I can't wait for the big suprise on Sunday!!
