Just looking forward, for those who may not have read:
After the series is over there is also going to be a made-for-TV movie directed by Edward James Olmos called "Battlestar Galactica: The Plan".
IMDB Link
From Wiki (which paraphrases what the Chicago Tribune wrote): "The Plan storyline show events from the beginning of the series, mainly from the perspective of two Cylon agents"
And of course the show Caprica is supposed to be coming out next year. I'm fairly certain that it won't be in the same style as BSG though.
