FSDT has made it clear that they have left the Prepar3d business
We made it clear we haven't, since our premier product, that is GSX, is still fully developed for P3D as we speak. We released an update *YESTERDAY* ( we still haven't found time to update the release notes, but it will come up shortly ), which adds a new useful feature for developers to integrate better with GSX, and will be used by FS Labs soon.
Airports are an entirely different thing, meaning we cannot ignore MSFS and, if we didn't took action fast, we would have ended up with no products to sell in the new sim, since MSFS is not directly backward compatible with FSX like P3D was, and a proper conversion requires a lot of work in any case.
Fact is, the MSFS SDK, even if it's not completed yet, so you still can't have your FS Labs/PMDG/Leonardo planes and we can't do a proper GSX *yet*, it's very workable to do airport sceneries, and lots of things it does, cuts dramatically on development time.
Explaining this is really out of the scope of a post but, the two main things that affect this are the way the simulator handles sloped airport/runways, and the fact it has proper realtime shadows and Ambient Occlusion and a vastly improved lighting engine, make it easier and faster to model objects and textures in a way that will look good in the sim. And this makes it HARDER to "port back" to P3D, because if we took all the things we added to update CYVR and LSZH to MSFS back in P3D, they would look very bad, like a sim from 20 years ago, because they have been made *assuming* they would run on a certain kind of graphic engine, which is very different than P3D.
Others have not, so you can vote with your wallet. I don't think it will matter is it seems clean that there's more $$$ in MSFS.
That what happens when people are voting with their wallets.
