According to KoenigRules at Skiffy,
BSG has been unofficially renewed for a fourth season, with an official announcement next week. I won't wholly believe anything until I see a SciFi press release, but Koenig has a fairly decent track record with this sort of thing. They'll air a TV movie in September, followed by 13 episodes starting in January. I can live with the shorter season -- even RDM has admitted that he prefers thirteen episodes because they make the overall arcs much tighter. (And thanks to grey for the heads-up!)
So, good news for this chilly Saturday. And now I'm going to curl up with some TheraFlu and orange juice, because I definitely feel my flu symptoms coming back. Ugh.
