Everyone seems to think that Red John is taking Jane on a journey, but I think it is Jane that is taking RJ on a trip.
I think Jane knows who RJ is.
If you watch how Jane works, he often designs a trap for the perpetrator. 
Jane often plays along with misinformation to lead the perp where he wants them.
I don't believe that RJ is on the list of 7 suspects-Jane set this up. 
I believe that some of the people on the list of 7 are complicit with Red John, which is why Jane doesn't get upset if they die.
I don't believe the clues on Sophie's recording to be completely true-I believe that Jane got Sophie to make the recording to help set a trap for RJ.
I think Jane will use some of the suspects as part of his trap.

That is all I have at the moment.

What I know for sure:

I would like to see Mashburn again-(and I think he might be RJ).

I would love to see Jane reclining on that sofa in his underwear.
New mystery to be solved: Boxers or briefs?
