i work in a big company and have to deal with information releases/PR all the time. I think what is going on is they know the results, and the results are not lining up with what they expected. Therefore they are either purposefully delaying announcing that data to closer to the end of quarter so the value of the stock doesn't plummet drastically in the one month left in the quarter (giving it less time to adjust before they close out the quarter to make financials look a bit better). Or they are having another company evaluate the data as a second opinion in an attempt to rule out the outliers in the study so that data looks more favorable than it is. I can think of no reason where the results are spectacular and they delay announcing it to the public. Clearly they had intentions of scheduling a press release (which they did today), so that release still went out but just talked about the partnerships instead of the data that was pending. They cleverly wrapped the bad news in with the "positive" partnerships to downplay the negative aspects (a standard PR strategy).
The only alternate scenario is Shiseido is somehow giving them sh*t for releasing their data at this stage and is holding them back; still, even in that scenario it would likely mean the data is not so good and Shiseido doesn't want their investment to go to sh*t because Replicel's data isn't what was expected.
As far as their tweet, let's be real guys. Replicel's CEO is almost definitely, without a doubt, reading these forum threads. I would bet my left testicle on it. That is why he makes the videos he did very recently addressing the customer base, and that is why he is tweeting about the lack of data.
