I don't know how long it will take, all told. I think VR has come farther than a lot of folks realize. Certainly hoping that folks buy this and it establishes a market.
I'm just far less sold on two points from Apple. First is the productivity angle. Is akin to the iPod being productive. Yes, it can happen. By and large, though, it is a consumption device. Would love to see numbers exploring that.
Second stickler is the attempt at using all gestures. Even Beat Saber benefits greatly from the feedback on my handles when I hit blocks. Having frictionless gestures just feels unlikely to be as nice as they demo. Reminds me of "Jedi" demos where you swing a light sabre. Neat, until you realize you can't pantomime getting blocked that well. Heck, even blocking is tough if you don't know when the block landed.
