Samsung already has a virtual reality camera in the form of the Gear 360, but it's not really for pros -- it's for everyday users who want to record a 360-degree video on the street. What if you're a pro, or a well-heeled enthusiast? Samsung has you covered: it's launching the previously hinted-at 360 Round. The disc-shaped device carries a whopping 17 2-megapixel cameras and six microphones (plus two mic ports) to create 3D (that is, stereoscopic) VR video. It's powerful enough to livestream 4K VR at a smooth 30 frames per second, helped in part by software that promises to stitch together immersive video with virtually no lag.
