Season 2 has now finished on Sky and has been excellent. With a nice finish ready for season 3.

Just seen on various websites the following:

The Sci Fi Channel will delve into the backstory of Battlestar Galactica with a new series that looks at the years leading up to humanitys devastation by the Cylons.
Caprica will be set more than 50 years prior to the events of Battlestar Galactica and focus on the lives of two families -- the Adamas (ancestors of future Galactica commander William) and the Graystones. Humankinds Twelve Colonies are at peace and on the verge of a technological breakthrough: the first Cylon.
As Battlestar Galactica is about a lot more than space battles, Caprica will be as much family drama as sci-fi tale.

Its an interesting premise as during the time period in question the Cylons achieve self awareness and fight the first war, which we€™ve been told was long and incredibly brutal.

Should be interesting if this does happen.
