Ron Moore said repeatedly "It's all right there" in the Last Supper pic, so let's take another look and devine the outcome of certain characters:
Roslin: Has rejected her newfound faith in the Old Gods but probably lives until the end, and is not going to end up being the "dying leader" since the writers just kept changing things up as they went along.
Natalie-Six: She points at Athena because that crazy-8 shot her. Will she be back for revenge or to seek accomodation?
Tigh: A Final Fiver who now knows his past, he doesn't seem to believe in anything except his floozy-boozy wife, Ellen.
Grail Cup: Supposedly the stand-in for the Final Cylon - so it represents Ellen - the font of knowledge since she rediscovered resurrection tech?
Lee: The Thinking Man, perhaps thinking about how boring they made his character this season. He sits with the faction that has closed the book on the Old Gods.
Baltar: Recoiling at Head-Six - she's baaaaack! Or did the writers just abandon her to the ash-heap of story-threads-we-didn't-know-what-to-do-with ?
Head-Six: She's in the Head-Six dress we've never seen Caprica Six or any other Six wear, and she's the center, so she must be pivotal. One would think, but given how they vomited exposition in No Exit and basically ruined the story, I'm not so sure we'll see her again.
Kara: She is one of the group that lived on Cinder Earth, the lady Anders used to sing his song to with that electric guitar. Is she Daniel? She was a woman, but reborn as a man on Caprica, then a woman again as Kara because Cavil poisoned her goo tank? Manly yes, but Anders likes her too.
Anders: He seems to love Kara - because they were lovers once on Cinder Earth or because she stuck by him after he got shot, or because he saw her glowing like an Opera Houser?
Tyrol: He holds a knife and there is no Tory. I guess we know who he kills. I guess he thought her murdering Callie was wrong, despite Tory and Tyrol being a couple 2000 years earlier on Cinder Earth.
8-Sharon-Athena-Boomer: Who can tell? Probably it's Athena, mother of Hera, still loyal to her husband Helo, who is such a dull character he should die before the show ends, but since he's in the pic, maybe he lives.
Adama: Sitting alone, facing out, looking inward - bitter? He sits with the faction with the book of the Old Gods open, althoug he's never expressed any strong convictions about any religious points of view. Perhaps he is just an old saw who can't see past his own limitations.
