I found this to be interesting also according to  http://tvbythenumbers.zap2it.com/2012/11/26/merlin-canceled-by-bbc-after-five-seasons-show-airs-on-syfy-in-u-s/158891/

Deadline reports that the fifth season of  Merlin will be its last. It will conclude its British run on BBC1 this Christmas with an episode that concludes the battle for Camelot. Shinw TV, the studios which produces the series, is considering developing possible spin-offs, though the showrunners Johnny Caps and Julian Murphy are leaving Shine to start their own production company. The final season of  Merlin will debut in the United States on Syfy on January 4, 2013.
