All - The reason few new planes have been released, and that good quality Airliners have not is very simple. At least twice a month MS/Asobo release one WU and one SU. Each and every single update, breaks the core sim, which reslults in a patch issue. It’s very, very expensive to create a plane in the first place (because of the convulated code/process this one is written in), and then twice a month, patch said aircraft because something in an update brakes my plane. They are waiting until the sim core and most of the ATC/ILS/NAV systems logis is set and firm.
Additionally, DX-12 is coming out. No one, and I mean no one, knows how that is going to affect the core code of this game, again, waiting to see how that all comes together. Announcements, are just that letting audiance know this is coming, my bet, Any real study airliner from either QW or PMDG is going to be mid -2022 or even later. I will be wrong, but that is my guess.
