Pink sheets can still shoot up. There's far worse companies on the pinks and OTC that have gone up a ton on BS fluff and hype. While not BS, look at what VRMLQ.PK did.
Bottom line is that there aren't all that many O/S and there's an increasing number of longs. As long as the sales increase and we get some big news the PPS should rise accordingly. We still don't know exactly what's going on with Lockheed. Confirmation of something really big with Lockheed and this thing skyrockets, even if it's on the grays!
