The 'switch off' or fluctuations for Series 7b are by no means unusual. So there's no reason to be concerned about people reluctant to tune in for fear of not knowing what's going on.
Indeed - previous two part finales give us some clues as to how little difference it makes:
7.51m - The Sound of Drums
8.61m- Last of the Time Lords
8.78m - The Stolen Earth
10.57m - Journey's End
There are plenty of viewers who won't be recorded in the official figures, and most (if not all) of the 'lost' viewers will be the same people who aren't that bothered and tune in and out through every series, but never have a problem coming back.
Plus - I suspect a repeat showing of 'Name' and some major recapping will be happening.
