Or 20 episodes and a two hour movie to air in September. Let's just say we'll have 22 hours of BSG. And AICN is saying that the movie/two-hour ep will deal with the Pegasus after the attacks, but I've also heard that the idea has been abandoned. Who knows?
Sorry for now links to specific reports. The news seems to be popping up all over and there is not a ton of detail at this point.
And before anyone laments the possible pitfalls of a longer season, the actors get paid per episode, so let's be happy for them. :)
