Sci-Fi has marked April 4th for the return date of “Battlestar Galactica.” The show will run for ten episodes while another 6 to 10 will air in the fall or next winter (because of the strike the fourth and final season of the series is being split up). Also, in the week leading up to the season premier, Sci-Fi will air two specials. The first a “sum-up” of the first three seasons and the second a behind-the-scenes/cultural impact of the show.
