Yes, Caprica is a sequel, but I always recommend people to watch it after they watch BSG.
And, I think I just watched that SG-U trailer 3 times in a row.
Rush looks like he's gonna be my favorite character.
I've always had a thing for the conflicted..
Spoiler
The fact that James Callis never got nominated for an Emmy/Golden Globe makes me want to throw up. ANY of Galactica's cast. In my opinion it is the best cast on TV along with Breaking Bad.
