A Sci-Fi Channel promotional preview clip of Season 3 is at this link . . . I don't think there's anything really "spoilerish" in it.

It seems to confirm that, while the ending to season 2 caused some controversy among BSG fans, it might also open up some intriguing story lines in season three.
I'd love to see Leoben interrogating Starbuck as one example. I wonder how fat Lee Adama is going to get. How crazy is Boomer going to get when she finds out her baby is still alive? Lucy Lawless is signed for ten episodes . . . . one can't help but think we'll see a serious fracture in Cylon society, maybe even a civil war. The comments in the clip above are clearly a present day allusion to America forcing the alleged benevolence of democracy on people unaccustomed to it (dirty leftist *******s!!).
A "Dualla" interview looking at her character in Season three . . . . . again, I don't think anything in here will spoil your day.

I think Sept. 19 is the release date for the Season 2.5 DVD with season three on Space in Canada starting sometime in October.
