Yeah, about that fourth season: ''It's very big,'' promises Moore. ''We're moving very strongly into the finale of the show. It's about getting to Earth, and what does Earth mean, and what is it, and where is it.'' Along with previously announced guest star Lucy Lawless (who'll pop up again for a few episodes as messianic Cylon D'Anna Biers), Star Trek: Deep Space Nine alum Nana Visitor will appear in an episode as a cancer patient undergoing treatment with President Laura Roslin (Mary McDonnell). Oh, and Moore says that, yes, he does know who the final unknown Cylon is; yes, whoever is playing that character knows he or she has been anointed; but no, they haven't shot the reveal yet (it will most likely be in the second half of the season).

Just when we get to see that half, however, is still very much up in the air. When asked about recent reports that Battlestar's final episodes may not air until 2009, Moore is noncommittal. ''That's a possibility,'' he concedes. ''No decisions have been made in terms of airdates and how many episodes they're going to run. There's a lot of factors, everything from there are other series they're going to have on the air [to] a possibility of a writers strike and how that affects programming. It's a complicated equation and there's no answer to that yet.''
