With a full readout of the DFDR AND CVR recorders, I hope BEA is still trying to get info out of the unprotected quick access recorders. It may not be trivial at all, but will probably be well worth the effort. May even open up new areas for the investigation. (Of course that can be a bit inconvenient when the report is almost ready to publish.
)
Comparable to seeing things with an earth bound telescope compared to the Hubble telescope.
