The BBC's in-house magazine Ariel recently went from online to print, but luckily it's now open to people outside of Auntie's club, and we can all have a snoop.
This morning they published a key quote from Beryl Vertue, producer of Sherlock, on the occasion of her address to theNations and Regions Media conference in Salford. While she couldn't yet give any kind of schedule for the next series hitting our screens, she did at least reveal when it will be filming.
And it looks like we've got a good long wait ahead of us - cameras won't roll until early 2013.
So, at the earliest, this would mean Sherlock back on screens in the Summer of 2013. There might have been a whole season of Elementary screened by then.
The first series aired in mid 2010, the second at the start of 2012, so the eighteen month break is at least consistent. We had been hoping for faster turnaround, seeing as series 3 was commissioned at the same time as series 2, but I guess that's not to be.
Who is to blame? Yeah, possibly.
