I've been reading some of the excellent theories, thoughts and reflections on this site.
The problem for me is to isolate what I think will happen from what I want to happen.
I would like to hope that:
The last season was a "long con" - an attempt to lead everyone in the wrong direction and to set us up for a surprise in season 7.
Or, maybe, they thought that the show was about to be cancelled and tried to wrap everything up in a hurry, but left space for an alternative resolution in case they got another season to play with.
Or, they were lazy and cynical in their approach to wrapping-up both the Red John and the "will they, wont they" Jisbon arc but will revise their plan due to protests from the fan-base and (perhaps) from the cast / writers.
If any of the above are the case then we can look forward to a cracking seventh season. They will have had time to finish off the Red John story-line with style. Maybe they could begin with the murder of Lisbon. Perhaps RJ waited until Patrick dared to love again before striking against him a second time?
Also, we should see the return of Lorelei. The ONLY way she could have known the names of Patrick's suspects was that her death was faked (remember, Patrick had not finalised the list until after her death).
Brett Stiles should also return. His death was obviously faked, plus he knows way too much about Red John. He probably also knows who he is. Maybe he uses him to dispose of people?
It is also likely that someone close to Jane and Lisbon was in the (stupid, stupid, stupid) Blake society. (This really was a low point - can you really imagine a secret group of corrupt cops running around quoting William Blake to each other?)
In the final reveal I suspect that RJ is someone you would least suspect - Rigsby or GVP, etc.
OK, so that is my desire - now what I think will happen:
Nothing.
More Jisbon crap.
More murder-of-the-week high-jinks.
And the grande finale? The wedding of the year!
A third possibility is that Cho will finally flip-out and get shot holding up a liquor store :)
