From the new DWM.
Series 7b doesn't start until April.
(So both halves manage to miss screening on those "dark winter nights" that Moffat claimed the delay was to allow the series to move to. And his "more Who than ever" actually turned out to be "one series in two years".)
The Anniversary Special (singular) doesn't shoot until (again) April.
(Anyone who was still holding out for any of Series 8 next year should really give up now.)
