The strike claims another favorite.

Effects of writers' strike head north:

"Meanwhile, the fourth season of Battlestar Galactica is stopping production tomorrow, and will remain out of commission until further notice, because it ran out of scripts, a source close to the show said. It was supposed to run until March 10. At least 200 people will be laid off in the aftermath...Mr. Vigars said the other real concern is whether, once the strike is over, these affected shows will be able to pick up where they left off. 'It's hard to get them rolling again,' he said."

I can't imagine that BSG won't return, but I think this does make a case for them splitting the final season in half. There's pretty much no way to get around it now.
