I believe VR Journalism is the future of journalism and the Killer App for VR: place multiple 360 cameras in the same area, and the area can be reconstructed to the degree a that a person wearing a headset can walk freely around the space viewing where ever they choose. Now imagine installations like that in Paris right now - being able to see and walk in the places the attacks took place, or imagine such an installation on the red carpet at the Oscars, or such a treatment for sports. Being able to project oneself into live, impact events and view them unfold is the Killer App for VR.
