I am surprised that no one who flew on the DUS-BCN segment has come forward to the media (or Reddit, or something.) Did no one notice the co-pilot at any point? What about security videos (as with MH370)? Surely those are being examined.
I agree the quick release of information was necessary to prepare families and everyone else for the shock of the truth. As horrible as it has been to process the information, I am glad they did it (and that it spurred immediate policy changes.)
