My guess is that these are the names that will be on Jane's list next sunday;

Dean Harken


Robert Kirkland


Walter Mashburn


Ellis Mars


Ray Haffner


Virgil Minelli


Richard Haibach

I'm not quite sure which one of these is Red John but if I had to guess I would say that he is either Ray Haffner or Ellis Mars. I know for a fact that Brett Stiles and Patrick Jane are not Red John. If it was Jane then everything that has happened wouldn't make sence at all and Brett Stiles was cleared of any suspicion in the episode The Red Barn. Ray Haffner would also make sence because he clearly has feelings for Lisbon which would explain why Red John hasn't even attempted to hurt her at least once.
