Interview with the BSG writer who did the finale:

The interview discusses all of the elements of BSG Season 3, so don't read it if you don't want to be spoiled. The interview is, at least, clean with respect to discussion of future episodes. One thing that it mentions, that I wasn't aware of, is that there's some kind of two-part "special" (i.e., made-for-TV movie) that will appear "this fall", so we don't have to wait all the way until January at least.
