...that they are very likely going to do a second series! Except with the episodes put online.
People who liked the first one, what do ye reckon to that? Good idea? Yea? Nay?
Personally, I think Catterick was one of the best things they've ever done, and that if it carries on in the same quality, then it can only be a good thing; however, if the missing years is felt, then it could get a little tired. But overall, looking forward to it if/when it happens!
