When are they going to be on again?

I dont know anything about the first two shows on your list but me and my hubby are both awaiting the return of Torchwood which we have both been hooked on since it started (and I dont even like Sci-Fi). The best I can tell you is that they were apparently filming in Cardiff in October but unlike the last two series this is more of a 5 part mini series (hope its not the end) its slated for airing in the UK in the Spring which means it will probably be the same here as unlike some shows this is usually aired concurrently here. Bring on the Spring.
