I just don't see the time delay in reading out the recorders as significant.
Sure the readers of PPRune would like instant confirmation that their speculation is correct.
Questions about the pre-crash integrity of the aircraft are easily answered in a day or two by on-site examinations in conjunction with review of ATC tapes.
The recorders are quite useful to confirm and/or examine what's going on in the performance of the crew. This should be a secondary-time-line issue and it's very important to take the time to select a venue that is free from conspiracy rumours among the seasoned investigators, with the exception of PPrune
