According to Zap2It there’s a Battlestar Galactica Prequel called Caprica in the works.

Caprica takes place approximately 50 years before BSG does and focuses on 2 families. The Adamas and the Graystones. The 12 colonies are at peace and a technological revolution is about to occur with the creation of the first cylon.

No word yet as to when this will be released and my buddy that works on BSG hasn’t gotten back to me.

SciFI now has some news regarding this.
