My interpretation of the announcement was that only 1 wafer has been received, with other trial/variant wafers to be receipted over an undisclosed period of time for further evaluation. Fred stated that the results would be announced as they come to hand, but as the receipt period for all of the trial wafers has yet to be confirmed, a time frame for release of results is also undetermined. They do not have all the required wafers as of the 3rd week of June as you have alluded to, and therefore I would consider this another delay.
For the record, I am a long term holder and would like to see this one reach its full potential, but I have seen this before, more than once or twice.
