SyFy Network has announced that their long-running series Eureka will end after its 13-episode fifth season. Originally the network was planning on bringing back the show for a short 6-episode final season, but it seems like negotiations fell through. Here is the short statement from SyFy:

After painstaking consideration, we have had to make the difficult business decision to not order a season six of Eureka. But Eureka is not over yet. There is a new holiday episode this December and 12 stellar episodes set to debut next year, marking its fifth season and six memorable years on Syfy. The 2012 episodes are some of the best we’ve seen, and will bring this great series to a satisfying end. We are very grateful to Bruce Miller and Jaime Paglia, their team of incredible writers, and an amazing cast and crew who have consistently delivered a series we continue to be very proud of. We thank the fans for their support of this show and know they will enjoy its final season in 2012.
