Red John will be either Bertram or the Sherrif. (If we can trust the list)

Rigsby will be killed by http://www.imdb.com/media/rm86617856/nm0631381 for his investigations into kirklands death.

Next episode I presume we will see Haffner killed off, a long with Stiles being ruled out. Although I would like to see RJ as Haffner, my gut feeling tells me it won't be him.
