w00t!! I'm a big Battlestar Galactica fan and just found out some good news. I snagged this from the forums at scifi.com
10, 11 or 12 more episodes in January 2009 officially, completing season 4 dealing with the fallout of finding earth, the head pple, the fifth cylon and all that jazz.......

BSG has now completed filming as of friday 11th July.

BSG will be broadcast in January to avoid the autumn sports season and up and coming new shows that BSG will have to compete with as well not to mention work in post production.
There is some confusion still as to whether there will be 10, 11 or 12 episodes, this is due to the fact that second half season length is 11/12 hours in total but the last episode could be 3 hours or the extra hours could be used in the new 'Razor' like movie.Nothing is confirmed as regards to this yet.
On June 28th 2008 in an interview with Grace Park in the LA times, she said that there was a greenlight for another Razor like movie with filming beginning in august. The movie will take place chronologically sometime during season 1.
