I honestly don't think the rest of the FS world would generate enough interest in vintage for MS to invest in it. It'll likely be third-party dev's that tackle that.
That was my thought. If the hangars are Missing as opposed to just generic models, that tells me there are plans to add them in the future. That could be a third party developer or Asobo is modeling them themselves.
Planes of Fame and Fantasy of Flight are both associated with MS. I remember years ago visiting Fantasy of Flight, and they had a bunch of sims set up using CFS I'm pretty sure it was.
