Great!
I would have been surprised had it not been, seeing as how great the viewing figures were for Children of Earth... I think Torchwood got a lot of new fans with it. And the dvd of the Children of Earth is selling hotly in the supermarkets and bookstores now, so the profile is high.
I'm glad we'll be seeing more of it.
It looks like there might be another series of Torchwood afterall! Take a look: http://www.comicmix.com/news/2009/07/25/exclusive-torchwood-picked-up-for-another-season-by-bbc/
