Many readers are interested in Hubblo VR (hands-on here), a 4k 3D 360 camera with livestreaming and realtime stitching. Hubblo will be launching on Indiegogo soon but in the meantime they posted
a couple of teaser videos a video from CES. (Update: the new CES video has been posted.)
Here is a video showing how their camera is used.
Hubblo said they will be posting a full-length video, and hopefully some sample videos from their camera.
