Tja, endgültig ist wohl nicht die Pause sondern das Ende. Zumindest laut Cinescape.com:

Executive Producer Tim Minear:
“We did get word tonight [December 12 – ed.], Fox won't be ordering any new eps,” says Minear, on his personal site. “That translates to 'cancelled.' We will finish shooting the ep now in production (I'm directing, in fact Joss came down to the set to break the bad news to cast and crew -- we wrapped early, but are back at it in the AM), we'll finish post on all eps, and Fox says they're going to somehow air all eps."
