One big assumption that I made here is that the things we have seen actually happened. What I mean is:
1. The people on the list, as far as we know from the first 3 episodes of season 6 and series 5, includes Red John in it.
2. When we see Partridge dying, that's what actually happened, he dies. We do not see him fake it so we assume he is gone. This leaves 6 suspects.
3. The description given of Red John from the blind lady is true. So list goes to 2 people, as they are the only middle aged and healthy guys on the list. Bob Kirkland and Haffner.
I say Haffner cos the dude is a creep.
Although, the promo for the 4th episode suggests one of these points is misleading.
