Large manufacturers like Fender are their own worst enemies, really. They've tried to make modern takes on the classic designs, like the 80's Elite basses & the 90's Zone basses, etc. But at the end of the day they're always going to follow the economic case & that's the simple point that many bass players are highly conservative & will stick with what they know, or variations thereof. So as long as people keep buying them, jazzes, precisions & mustangs will be the order of the day. Simple as that.
The only way to change that is for people to stop buying them. Like that's going to happen!
