Now let's be honest ...
In my eyes it would make sense at all to equip aircraft with another update!
It's just not really much fun to fly an aircraft, which has front and back problems yet.
Certainly it is nice to build new aircraft, but the customer should not be penalized for the new aircraft are always designed and purchased to be neglected.
It would be nice to know what steps are being made, and how far it looks for updates to the "old" planes.
