Spoiler below..
If you download the app sidereel and look up the mentalist guide the episode guide has a preview of the episode after the red John reveal its called my blue heaven and looks like the show is going to fast forward 2 yrs ahead after rj is caught the info says " Two years after the red John case was closed, Jane receives a surprising job offer that could change his life." Looks like the show may go in a different direction after they reveal red John.
