Really interesting topic here!
I wrote with 29 Palms about one year ago if there are any plans on updating EDDB. The developer said, that they are currently not working on an update, it is planned to bring out an update with the real opening of the new airport.
As I am now reading from Aerosoft that it is not planned to update the addon, I am asking if there is a misunderstanding between the developer and the publisher? If no, I don't understand the reason for the change of mind...

Also, I never quite understood why the X-Plane 11 EDDB version is more up-to-date compared to the P3D Version, even though a professional version was released with P3Dv5.
