This forum has mentioned 500 for 2019 and 750 between now and next March.

Already Hired 80 or so so that leaves 420ish in 2019 and then another 280 before March.

That’s an average of 45 a month for the rest of 2019 and then 90 per month in 1Q 2020.

Seems to jive with what has happened in classes and well within training capacity.
