Enhancing the 737-9/10 any further is pretty much flogging a dead horse. Boeing needs a clean sheet design to address the A321LR and XLR and the goal should be to surpass these jets. Unfortunately Boeing’s cash situation is poor and the KC-46 is another disaster program. The long term potential for the 777X is probably a concern as well. They have payed off significant numbers of engineering staff. The COVID order slow down will allow Boeing some breathing room to develop something new but given their record of late, a new jet will be a long time coming.
