I don't believe Ed ever actually specified when they were actually hired and or started, please correct me if I am wrong. All we got was a pr stating that they had been "engaged". Assuming that the date of the PR is the date that the auditors began is reckless and irresponsible without further indication from the man himself. My money is on auditors were already auditing at the time of the PR. Pure speculation, of course.
Having worked with auditors in the past, I'll bet you a dollar that they've given an eta for completion, Ed has merely not communicated this with us and rightly so. I can only imagine the drama that would ensue from auditors giving an eta, Ed relaying that to investors and then due to unforeseen circumstances it taking longer. (Think post Q4 release daramathon).
They could already be done for all we know, we'll learn more as the story unfolds.
Ed has shown time and again that he is methodical and these things will be released according to his timeline and no one else's.
Judging by the past two months, I'm perfectly fine with that.
