I'm pretty sure EPGL, given a time frame, would choose the latest date as they alway do. You say APRIL-JUNE. More likely it will be JUNE if we're lucky. If EPGL see us all satisfied with long delays by our happy posts on this board, they may even try to shoot for next fall sometime as the release date.
You seem to be under the impression that the company has launched the MPDD, and is simply choosing to not disclose their sales numbers. It has been pointed out to you, however, that the product HAS NOT launched yet. Given that, what numbers are you wanting the company to announce?
