Here is my take on the situation.
MDGC is probably broke, but is on the verge of launching what they have described.
So the stock PPS goes down ... so what! Theoritically it could be a lot higher but maybe MDGC is doing nothing. Holders would be (temporarily) happy. Alternatively the PPS could go a lot lower even though MDGC really is going to successfully lauch their products.
In reality we don't know much of anything. So the PPS could drift higher or lower until we actually do know what's going on.
PPS probably doesn't reflect much at all. It may rise if some buyers show up on spec, or it may fall if holders get bored and decide to dump. All random events.
We really don't know one way or the other what MDGC is about to become. So the bottom line is (as usual) patience.
As so many have said in the past, its all speculative. Buy and hold and you might become a millionaire. Buy and hold and you might loose it all. That's the nature of this and many PINK companies.
Demanding "to know" what is going on will solve nothing. If MDGC really has the goods, they will prove it to you when THEY think it is the appropriate time. No fluff PRs in the meantime.
