I doubt it too, but I think at 400k confirmed cases, you can already 'bank' around 40k fatalities if you stopped all new cases coming in and waited 4 weeks for them all to resolve. A wild guess might put us around 500 - 600k confirmed cases in this wave if things settle down and don't really explode in other heavily population centers. Government models are showing expected ~60k fatalities now, but I'm not sure what expected fatality rate they are using and they don't really show the expected confirmed numbers.
I guess if we assume 80% mild, 20% need hospital care, they are anticipating needing 95K beds at peak. So they are anticipating roughly 95 / .2 = ~475k confirmed cases at peak before things start to drop and we get less and less cases coming in. Seems roughly right, or we might not get there. But you'd probably have ballpark 600K cases by the end of it as things tail off.
They are looking at about 60K deaths total, so it seems to me like they are expecting about a 10% fatality rate from 600k cases confirmed, with 20% of those confirmed cases requiring hospitalization and 50% of those hospitalized being potential fatalities. Also seems about right to me.
