Wikipedia: Series 8 Airs on 13th October!

[Nitrus]

Traffic Cops is presented in two formats... an hour long episode which is aired for every new series, and repeats are aired as a 30min cut down episode to fill in gaps.

I believe Hustle is due to air early next year as it did last year, so I doubt these shows will be aired close to each other.

I think the BBC will slip it into the schedule with like a weeks notice.
