Orbx has already stated that they will upgrade the models in their pack. So begins the tricky process of addons into a MSFS2020 world that has good models at ground level and photogrammetry models that look terrible at ground level including all of the solid bridges. The addon developers will have to be careful about what they replace with an addon. I expect this will get even more interesting when MSFS2020 does a Bing map upgrade and the terrain overlay and some photogrammetry type models change.
