In 6 days, we will hit 400,000 dead (using Worldometers - 3 days later with Johns Hopkins' #s). A month after that, at the latest, we will hit 500,000 dead. And 600,000 the month after that day.
It's better if the IHME prediction is right and the rate of daily deaths starts to plummet in two days. I just can't see how that would happen, as it is not predicated on the vaccine's being rapidly deployed and would seem to ignore the impact of Christmas/New Year's.
