I'm actually shooting VR
The know nothings did all the usual PR crap - hanging cameras from drones and flying over Iceland, putting you on stage in Blue Man group etc, which is a 1 minute wow, but not a long term connect.
VR phone goggle shows the potential but simply isn't good enough until screen resolutions go up 5fold from current top end.
VR will hit either via games (which I don't do) or when film makers (and actors) work out how to tell stories in VR, a system that kills all the usual tricks based on shot and camera placement.
It's a modestly priced add on to your existing PC, NOT something that needs a high end machine that you don't own yet.
I'm playing with VR filming not because there is a market today, but because it's interesting. No one knows anything, and that's always fun.
FB are probably right to bail from production because they have enabled the WOW and now they need to wait for makers to develop the craft, and that can't be hurried. They should focus on next gen kit - trying to hit that quality/price.
If I was FB I'd even see some commercial logic in doing "A Container" - invest in the work and make available to all mfrs, on the grounds that successful VR equals more, better, eyeballs. Much like the guy who invented container shipping.
