Longtimer,
Covid19 aside, at some point fleet aircraft will become uneconomic and require replacement. Traditional Boeing buyers have the choice of 737 Max, which would reduce type training/conversion costs (Don't go there!), A320Neo, or, the Irkut MC-21 and Comac 919.
Russian or Chinese, got have balls of steel to go with that, Airbus have a considerable backlog of orders (for the A320) and Boeing will be discounting heavily, they need Max's in the air clocking up reliable air miles.
This will be a win for the bean counters, if, the MCAS saga is finally put to bed.
