I would say that 9million is a certain - though for 10? Random guess : 93% chance - depending on the effect of Amiibo's and how much Hyrule Warriors sells.
Edit: Actually seeing your brakedown with those quite low boosts Sept/Oct (and not exactaly mentioning JPN releases this month and B1/2 a month earlier), I really think this is my prediction:
10.4 Million!!!! =D For comparsion, I think PS4: 15.8m and X1: 8.0m
