Syfy has purchased basic cable rights in the US, with Hulu getting streaming rights. No airdate has been posted to my knowledge, but it may be added to either Monday or Friday nights. Since Continuum will air season 1 back to back with the upcoming s2, that timeslot's a lock thru late spring, leaving it a candidate for Being Human or Lost Girl's timeslot, or replacing Merlin on Fridays after it finishes it's run.
Merlin is the closest of those to being done (for good), so I'm thinking that seems like the most likely place to put this.
Wait, what day is Defiance airing?
Defiance is slated for Monday nights. So it could be Continuum, Defiance & P:NW on Monday.
Syfy also picked up SkyTV's Sinbad-that could get the post WWE Friday slot after Merlin wraps.
