The season finale threw a huge curve into the story, with President Roslin losing the election to Gaius Baltar and his decision that the colonists would settle on New Caprica. Cut to a year later with Baltar acting like some contemptible Roman emperor when suddenly the Cylons arrive to subjugate their settlement, as the two battlestars escape to regroup.
In case you weren't aware, SciFi.com has been showing two three-minute "webisodes" per week for the past five weeks which bridge the gap between the Season 2 finale and the Season 3 premiere. These mini-episodes show some of the daily goings on of life on New Caprica and the growing resistance movemet. Today SciFi also added a "First Look" at the premiere which consists of the first 13 minutes of the show (for those of you who can't wait). :-)
