Filming should begin sometime in July 2016 and run through April 2017.<br>

Possibly Season 12 will start on Mon, 11 July 2016 -- based on 2 tweets at the end of Season 11 saying they had 82 days from the end of Season 11 to the start of Season 12. But often the production office opens one day before actual filming starts, so filming could begin on Tues, 12 July.<br>
