up until AMSA the reports of more pings were wsj, a us official, although volcnicash in his post on the 16th said the briefer has confirmed it, I have watched that but it is not in his "speech" so i am assuming it was a question/answer
However the AMSA guy stated there were 6 more pings which have been analysed
I guess they will not release the other ping data. The arcs from the last ping made the public point that MH370 wasn't in the South China Sea. After that there is no up-side to releasing more data - it will just spawn loads of duff amateur analysis (including my own) that doesn't help them in any way.
