As you noted, this is what they stated about putting out the audit before the end of Q2 in the April 11, 2013 PR:
We expect the twenty four months of audit history to be completed no sooner than the end of Q2 of 2013.
Unfortunately, in last week's PR, they did not mention that timeline, and appear to no longer have a self-imposed deadline.
The following quote is the closest thing I can find in the PR that covers the uplisting and the audited two years. Note that there is no mention of a twenty four month audit history:
As stated previously, the Company has retained an auditor as we work towards an up listing of our stock. Our goal is to make sure that all reporting is done accurately and in compliance. This has been a cumbersome process and the DTC chill has caused a significant delay. However, the Company has allocated the resources needed and is diligently working towards this realization. It is not known at this time how long the process will take, but we will keep shareholders updated on progress.
It looks like they're blaming any delay on the DTC chill, but in the company's defense, it's a little unclear whether they're planning to update shareholders on the DTC chill issue, the twenty-four month audit, or both.
Still, I've searched the press release for any mention of the twenty four month audit, and haven't found one yet.
