Mathijs Kok has recently made a post via the Aerosoft forums showcasing Brussels International Airport renders. Although the scenery is intended to be for Prepar3D V4, the tools used are more aimed at FS2020. On the previews, we can see a jetway model or VDGS system, for example.
There is not much we know from the post, but it’s clear, that Aerosoft is preparing for MSFS2020.
