(Not directed at you, @inbetween but just spring boarding off your post.)A limiting factor on what though? The 737 is meant to be cheap and cheerful where any gains are always going to be pretty small and certainly invisible to passengers. The big buyers such as Ryanair and Southwest are very cost sensitive, they just want low costs above all else and new designs always represent higher costs, at least initially. The 737MAX has actually sold very well specifically because it is a reused design.
Newer designs are also a bit of a risk because the long term costs are mostly unknown. Manufacturers may use new and lighter materials such as carbon fibre for example which sounds great. This isn't great though when it turns out that repairing those materials costs a lot because they're more complicated.
Airbus are no different to Boeing anyway, they recently re-engined and rehashed their A320 and A330 which are both 40 year old designs. The only new aircraft that Airbus has built recently is the A350 and that only came to exist because their 4-engine programmes (A340 & A380) never sold well and were eventually killed off. Without the A350 Airbus would have had a gigantic hole in their assembly lines.
Two A321neo engines blew up recently, but no-one seems to know or care, so no biggie, eh?!
