Hi Ben,
There has been much confusion on this, including me. What I understand now is the FAA was going to propose a their spec in June for the new weather services, and actual implementation into the ADSB system would be further down the road. We're keeping our thumb on this, haven't heard anything yet about the new data.

Walter, any chance you could say how you came to that understanding? It may be true, but is not what was widely reported. According to this story six weeks ago, some of the new data started being broadcast in parts of the US on May 9:
From http://www.rotorandwing.com/2018/05/1...-deployed-june/ (emphasis mine):
Key Site deployment (first time these products will be broadcasted by external radios) started May 9, with remaining deployment across the country projected to be completed by June 7.
