In order to do Stereoscopy properly, you need the axes of the camera barrel to intersect having a set of cameras all radially pointed outward doesn't achieve this.
I'll be interested to see what data they're sending to the video player to provide both stereoscopy and 360-panoramic video at the same time. The methods I can think of offhand require real-time pixel-shuffling to assemble the proper view during playback but maybe they figured out something else.
