No. It's been done for a few years. They started a prequel called Caprica that explained how the Cylons came into being, but then they cancelled it just when it was getting good. They are in the process of developing a new series called Blood and Chrome which takes place during the first Cylon war when Adama was a young viper pilot. Should be coming out later this year or early next year.

I've go the whole BSG series on DVD and it's available on NetFlix. The last two seasons are phenomenal!!! Without a doubt the most creative and imaginative series I've ever seen. The best thing is it's not your typical SciFi series. I love how it takes place in space but it's not about space. And they run out of ammo, fuel, food, etc... The show is literally about the characters and I think that's what made it so good.
