Truth beign told, the price drop of Oculus, which is quite dramatic, was pure despair. Their hardwarwe, although being the doorkicker, does or did not sell well, they had to react. HTC Vive has sold roughly twice as many, and Sony even 4-5 times as many (late summer/early autumn).
I expect that prices going down, but whether it will be so dramatic so fast as with Oculus (-50% in less than one year), I have my doubts.
