Who is the final cylon? That is the question. As Season 4 rapidly approaches and BSG fans purchase the newly-released Season 3 for a quick refresher, this vraag is resting on everyone's mind. But the problem with placing bets on the final cylon is that the writers of BSG have zei that they don't plan an entire series from the beginning (the way Joss Whedon did/does) and so it's difficult to anticipate their selection. I must admit that I was entirely surprised door the four humanoid cylons that were revealed at Season Three's conclusion, which makes me second-guess any of my predictions....
