I have to say, in responce to the Facebook discussion link above, that I don't understand how Levine's admittedly vile and vitriolic responce to the delay is the cause, and effect of it?
The BBC wouldn't care. Some individual people would, but the bureaucratic machinery would not, and no amount of Levine's bitching or fandom's excitement would sway the bureaucratic machine off their course.
It's possible that Morris has seen fandom's reaction, Levine's outburst, etc., and gotten cold feet. That's the party that's most likely to be swayed.
I remember the days when [Levine] used to wheedle his way into press screenings to confront RTD or whomever about whatever stick was up his backside at the time.
Like the time he confronted BBC people at a press screening and demanded answers about their plans to cancel Doctor Who
at the end of the fourth series? And then he claimed he had saved the program from cancellation when the gap year and Moffat were announced? Great moments in history, there.
