Since we have to wait till the Fall to see another episode, I figured I'd try to get some theories going on a different question:

HOW will Red John die? (if at all)

Here are some possible theories I came up with:

-Jane kills him like he said he would all along
-RJ kills himself before (or during) his capture
-Lisbon or Kirkland (or another agent) shoots Red John because RJ is about to kill Jane
-One of RJ's followers kills him when he gets captured, just like all of his accomplices were killed, before Jane has a chance to kill him or bring him in

Any other theories?  Or additions to my theories?

**Also, side not--  I put Kirkland in one of those theories because I still believe he is a good guy trying to find Red John.  I posted a theory that he was a good guy after the episode that he shook hands with Jane and people started thinking he was bad.
