To me the problem with the Vision line is it doesn't give any compelling reason to want it now or in the imminent future, even if it were priced similarly to lower end headsets, to really drive large numbers of sales on yet another VR walled garden. There is no killer app you'll spend hundreds of hours in, it's not going to actually replace/upgrade using your traditional apps, VR gaming is already relatively niche in established and open marketplaces but this has a brand new walled garden marketplace, and it offers nothing particularly "revolutionary" people haven't been promised 100 times about VR/AR to be disappointed with already. If it offered something meaningful against all of these points then it'd still sell decent numbers even at $3,500 but the problem is it's just lame despite being so high end.
