The A320neo caught Boeing off-guard, but barring a major unforeseen issue the 737MAX will be a big moneymaker for Boeing until the all-new 737 comes out in 2030.
I bet you there will never be an all-new 737. I'm sick and tired of this 'type-commonality' excuse that Boeing is always quick to point out. Real truth is that it is a cost saving gimmick.
Just give us an EICAS!!!! That is clearly too much to ask for
