I want to clarify - we are considering the FS version, but not right now, currently I don't even have fs20 (didn't buy it) and FS doesn't even have a demo version (shame on them) as Laminar does and it was very convenient because the XP demo was fully functional for testing any interface.
And we cannot allocate time for this now and there is no reason to rush, we are not a commercial company, this is a hobby, and if some other interfaces are good for FS and XP - it's good, we can continue to work on improving and extending HCSCI for XP.
Besides, we just think that X-Plane provides much better and more convenient capabilities for building a cockpit, modelling the systems, and it's nowhere near the end of development (made evident by the recent engine update for Vulkan compatibility).
After my many years of experience with MSFS (since the middle of 90th) I found the X-Plane (in 2010) as much more realistic in terms of aerodynamics and especially for GA/VFR flights - it is a real flight in real atmosphere after FS "arcade/programmed" flight.
For those who prefer to fly in VR helmet, no need to have a hardware cockpit at all.
