I own the ricoh theta s which is a $350 consumer 360 camera and love it. I take it to friends weddings and people lose their minds at how fun the 360 pictures are.
I think that if Ricoh makes a followup camera with better resolution, it should be HUGE. The current Theta and Theta S have already enabled a lot of people to "hack" with it :)

The Theta S's quality is almost but not quite good enough for what I want to do, so I eagerly await the followup.
