This is a good recap of all thE VR gear at nab 2016. I kinda like the 180 stereoscopic images with side by side video viewed with some vr goggles. However 360 monoscopic seems to be all the rage. I get that it's useful for something like a real estate video but other than that I just don't get what it's really useful for. It's cool that new products and software is available so you can produce 360 content but I can't think of anything I'd want to shoot in 360.
