Fan-frakkin'-tastic!! Some good, solid answers. There are still plenty of questions, and in some cases these answers raise even more questions, but this is exactly what I was hoping for.
Among my new questions: Anders says "Organic memory transfer came from Kobol along with the 13th tribe." Does this mean that the Cylons were created not on the Colonies, but on Kobol?
So far this has been the show's strongest season for me; I just hope the ending holds up.
