You don't invest in the future once you're already there, Hotstart should lead the way encouraging more users to adopt. With them already partnering with SimVRLabs that's a good start, but if they continue to push VR support for this and their other aircraft then that can only be a good thing.
Once Vulkan arrives I think we'll see the VR population increase as right now VR has compromises.
Likewise the VR industry is moving. Oculus are announcing a 1.5 generation headset soon, the Rift S, with even greater tech to come ( see half dome).
I also think VR will bring a new generation of simmers. For me personally I never had an interest in aviation, until I tried the xp11demo with the Rift. Since I've been hooked.
I had tried flying on the monitor at multiple times through my life, but never cared for it.
Being sat in front of a screen is no comparison to being inside the aircraft. Clicking things with the mouse is no comparison to reaching out and grabbing levers and flicking switches.
That's my ten cents anyway
