I am going to guess 45k/week on average. So with 510k unit +9 (months) *4(weeks/months)* 45k units/week = 2.13 Million units.
40k/week or 50k/week aren't too unreasonable either so, will assume an uncertainty of +/- 180k.
So my final answer is 1.95 mil - 2.31 mil, or 2.13 Million +/- 180k.
This is assuming we are talking about December 2017 and not a fiscal year calendar.
