I see BBC1 controller Danny Cohen has stated that there are too many male detectives on BBC. Which is fair enough, but he went and threw the baby out with the bath water by cancelling the excellent Zen. Shame, as it and Wallander were the only UK 'tec shows I've watched in an age.
Anyway, back on topic, these shows do indeed look promising, though I've missed Exile. Apart from Doctor Who and Torchwood The Shadow Line is probably the one that interests me most (and not just because it's got a former DW in it!).
