You will remain a Yamaha fan for a long time, based on the D+M new lines timeline. Based on price and Yamaha's next move (such as offering DL an option too), they may actually outsell D+M too in the long run..
DL's license fees will become more affordable, to the OEMs anyway, due to the huge increase in volume, that is after 2023 if D+M (already sells a lot now) start may start selling AVRs/AVPs like pancake.
