I agree that in all likelihood, they want to avoid leaking any sensitive information, even to larger shareholders. The LAST thing they want to do is screw up now, of all times. From what I understand, they have a set schedule for events pertaining to certification (which, of course, might need to be adjusted if some unexpected event occurs), so a consistent slew of press releases isn't out of the question from now until whenever the certification PR is announced. 

I do not expect a formal press release. I'm surprised you're counting on one, because a Form 8K usually suffices in these situations. A PR usually goes out when they get institutional funding, not from one individual, unless it happens to be Icahn or Soros. And interestingly enough, if you look at many of the criticisms from the bashers on IHUB, they pick them from SEC filings, not press releases. 

But then again, anything is possible.
