Use in upcoming supporting flight sims like Battle of Moscow?

( Forgive me if I am posting this in the incorrect place.)
In the next few months Il-2 Battle of Moscow & Cliffs of Dover flight sims will finally support VR and many people like me will be upgrading our computers & buying some form of VR gear.At least initially the sims will use Steam support and so far as I can understand this favors Vive over Oculus, but thiis may change .My question is obvious :will Pimax be a choice that will work as well as the usual suspects for flight sims such as these or are their drawbacks with Pimax used with flight sims that require moderate FPS & definition?
Also will the upcoming 8K on this or any other sytem make it worth waiting for?
