The quote you provided, at best, suggests The doctor may have had some suspicion that some entity connected to the phrase 'the silence' may possibly be responsible, but he had no idea who or what they were and certainly no idea the actual person responsible, which come to think of it we still don't know to this day, or even how they did it. Had the same thing been done in an RTD finale we'd have had an explanation of exactly how the person was able to break in to the TARDIS,how it was possible to blow it up, and the exact culprit possibly with a flashback actually showing it.

Moffat kept talking as if he had a plan all along, which if it were the case he would know that he already had a rough idea for a final story that included all the explaining elements naturally within the narrative of that story and were important to it, so wouldn't have needed to 'respond to demand' by addressing those points in a hurry, but what we got seems to show that he hadn't come up with answers when he posed various questions or situations and did indeed, only because of demand, finally come up with answers in a rushed, poor fashion which although did technically answer the points, still felt ultimately unsatisfying to brush over the resolution to points which were made out to be a big deal when they were introduced.
