New found post.. This sounds like there is an SDK (But it will not be finished and available Aug 18) and another post said that all files are open to edit like CFG's But it is probably obvious there are no (MDL's) Bgl's and it is definitely (Not X-file format ) or (XML) so no (Makemdl) FSDS is out Gmax and 3dsMax probably out.. The way this reads is like it may be a year later before 3rd party will be able to catch on and make freeware or product....this post below tells us that the transformation (Is in a total different format) Of course (That is in a way expected) to get better graphics.. looks like 3rd party are in for a longer wait,, So at least a little light on the subject and patience.. We will all have to (Go to school again)

Scenery developed UK2000 Scenery has taken to Facebook to share some insight about their current development progress for the all-new Microsoft Flight Simulator. On the post, they seemed surprise by the release date announcement by stating that the SDK for the new simulator is not even complete yet.
Speaking on their Facebook post, UK2000 Scenery said the release is “is far sooner than we would have thought,†before then saying “especially considering the SDK is not complete.â€
This is the first time a third-party developer has been quite so open about the behind the scene developments of the new sim. However, Microsoft has said over numerous update posts that they are working closely with third-party developers to get the SDK ready for them to build addons for the new simulator. As recently as June 11th 2020 Microsoft confirmed that SDK was being worked on and said they were making good progress with it.
Commenting on what it is like to work with the new simulator, UK2000 Scenery has said that this is like converting something from “Windows to Linux, it is totally different in every way.†They also said that Microsoft Flight Simulator uses all new modelling formats, AFD structures and a new terrain system meaning the current tools and workflow is very different.
