Hi,
The BEA isn't a press agency, its missions don't include,
AFAIK, to release ASAP all gathered data.
They have (and will) release intermediate & final reports when those are finished/ready/approved.
Indeed .. but methink his mission is also:
"If necessary, recommendations of security measures will be made urgently to prevent the accident from happening again"
And it's seem that BEA (maybe in the shadow) had made already one concerning the AF447 case ... as AF revised by a technical note how manage plane when incoherent speeds are read and also send all the pilots to a new (improved?) sim training for that.
