I knew the 7 billion wouldn't disclose proprietary groundbreaking technology. Helps them keep their competitive edge. Apple, google, Microsoft, Samsung, never ever announce technologies they are working on until they are ready for the market. That is how the big boys play. Welcome to be playing in the same arena as the big boys!
My guess is that the company is withholding info. for the confidence of their own stock holders. They probably want epgl to be listed as SEC reporting, and they may have another requirement before releasing this to their own investors. They have to think about their pps. too and time the release correctly. That is just my guess.
