Will we see one more season after this?
At this point, having followed the show since Season 6 (Watched the first five on DVD in order), and everything that has happened since the Season 6 fiasco, will Season 12 be the end or will they aim for one more? Despite all the cast changes, I feel that they should all come together for the final three episodes of the show (With the exception of Jayne Atkinson's Erin Strauss and Mandy Patinkin's Jason Gideon, whose characters died in Seasons 8 and 10 respectively). Nicholas Brendon may be a possibility but I'm sure they could get them all together for the end of the show.
