You're right Witty, he's not been good on timeframes...
There's something else here, the audits, particularly for year ending March 2016 is only a part of the 10K and we've heard enough to suggest that there's lots of other stuff going on: litigation, acquisitions, getting rid of Smith/Morris perhaps, debt reduction, change of CFO etc etc.
There's every chance that all of the audits are complete and may have been for sometime, he's just waiting and getting all of this other information ready to "drop a bunch of news all at once..."
I agree with your line of thinking...
