Here's a thought...
Does anyone know exactly what we've supposedly been told will happen in episode 8 this year? Because I wonder...
Do you think there's any chance that Red John's identity is going to be revealed to the audience, but not to Patrick Jane...?
In other words, could it be that our hunt for Red John will be ending, but their hunt for him will still continue?
Alternately, maybe they learn who he is, but can't do anything with that knowledge yet. For example, what if they learn Red John is the man in charge of the Tyger, Tyger conspiracy within law enforcement?
That scenario could probably play out two ways:
1. If Red John knows that they know who he is, then he'd almost certainly try to eliminate them. One or more of them would likely have to go on the run, and they'd have to work outside the system trying to find a way to bring him down (possibly with one or more remaining "on the inside" if RJ doesn't know that those people know, etc.) For example, Jane and Lisbon might have to hide/run/work in the shadows, while Cho becomes the new supervising agent at CBI or something (and tries to help them when he can).
2. If Red John doesn't know that they know who he is, then things proceed more similarly to the way they have been, but with the focus now on exposing Tyger Tyger in order to be able to bring down Red John.
Of course, this is just one possible idea. The general thought is just wondering whether revelation of Red John's identity will actually end the Red John story arc by bringing some kind of end to Jane's quest for vengeance, or whether it will somehow transform the nature of the quest rather than ending it...
