From Ask Ausiello:
Question: Any scoop on Battlestar Galactica?— Ananya
Ausiello: All you guys praying to the Sci Fi gods to increase the show's fourth-season episode order from 13 to 22 should be careful what you wish for. My friends over at syfyportal.com are suggesting that those nine extra episodes — should they be commissioned — would actually be used to wrap up the series. As in permanently.
And here is the link to the SyFy Portal story.
I think many of us were predicting season 4 would be the last so this isn't exactly surprising to me if it's true. And as long as the series gets a wrap-up I'll be happy. My one problem with this is that the BSG movie seems to be a go and I thought that was part of a possible twenty-two hour commitment. So, now that's separate? Maybe we'll get some straight answers once this season is over.
