There's too much confusion.

"'The decision was to end the show at the top of our game,' said Moore. 'That choice precludes certain other choices. [Like wrapping up every possible loose end of plot]. We'll always be able to say we could have done more.'" TV Week offers up the details revealed about BSG season 4 at Comic-Con over the weekend, including who's returning, who's being focused on, and when the final Cylon will be named. (The fact that Moore admits there're now two Cylon-hybrid kids after the bizarre, Dylanesque Season 3 finale, and that one's just being ignored while the other (Hera) is crucial to the S4 arc, further suggests to me that they really didn't think through that goofy end-of-season reveal very well.)
