Time is the key to it. WHY?
Let us make here a situation..
PMDGs last product in line will be the 777 ,747V2 and DC-6. What After that ?NO more development?
They don't have any new aircrafts to make(May be they complete the past boeings like 767s/757s) & the new ones cannot be made due to these limits.
Nobody would want utmost company like PMDG to close.. They are the reason why people do Hardcore simming
I remember the times when features that were said impossible 5-6 years ago are now made possible.Example totally a different FBW systems working independently,ENGs ,WXR. working independently outside FSX.
Where there is a will, there will be a way.
