BSG webisodes on Scifi.com
I was happy to see that they aren't sticking to the Nov start date and the new season will start in Oct. They are airing little 3 minute webisodes on scifi.com to tell a small part of the story that happens between season. They have 3 out now, and are releasing every Teusday. Seven to go.
