It is believed viewers will have to wait quite a while before they actually get to see the finished episodes.
Based on the timing of the last two series, and the Christmas special, the new three-part run is more than likely to arrive on New Year's Day in 2017.
Earlier this year it was reported that the BBC series would be shot on the outskirts of Cardiff at Pinewood Studios in Wentloog.

The Welsh government - which has a £30 million media investment fund - is thought to be giving financial assistance to the project.
Details about the plot remain under wraps with creators Steven Moffat and Mark Gatiss remaining quiet.
Sherlock series 4 will air on BBC One in 2017.
