Re: Officially no series 8 in 2013
And given that the only episode that's an almost total blank is the finale, I guess that's where they'll be.
A good guess every Doctor Who finale (proper finales, not mid-season finales like A Good Man Goes to War or The Angels Take Manhattan) has featured either Daleks or the Master.
