We confirmed multiple times along the past months we are not planning any new airports or major updates for existing ones for FSX or P3D.
It's possible we might consider releasing an update for KCLT in P3D, because the work we are doing to convert it for MSFS included adding a new Terminal and a new Control tower that opened after the scenery was released in 2017, but we are not 100% sure about this, because sales for P3D has been constantly declining, especially in 2021.
The same might be valid for KIAH, since it will be also released for MSFS after KCLT, and it will also include the new Terminal C which is missing in the current version. This is also *possibly* a candidate for a P3D update.
Other than these two, we don't have any plans to update older sceneries for P3D.
The only product that will continue to be updated for all simulators is GSX, because the GSX logic itself ( which is the most important part of the program ) is almost entirely unrelated to the simulator version.
