I have a streaming volumetric video chat prototype. I plan on launching private beta this month. I also have a portable hardware display that I guess you could call a phone that I'm working on. I expect it to be testing with a small group by Q2. I'm petty excited about 2019. 5G makes things a lot easier and really increases how people can interact with the content.
Just for reference, streaming point cloud is about 100mb/sec. You can compress "frames" with the totally unproven Google Draco product, but there's nothing quite like mpeg for the format. I guess it's really hard to call it a format since there's no real standard at current.
