I got to see the Sphericam Beast and Sphericam 2, two professional 360 cameras with livestreaming capability. I got to meet their CEO/Founder Jeffrey Martin and their CRO Gaja Zornada. They showed a livestream from each camera and they both looked very good from the large LCD screen.
According to Jeffrey, they are working on improving the Sphericam 2, and will be launching it in early 2017. Here is the official Sphericam website.
