IMO, it seems that the company has not been concerned about the dwindling pps. They seem to have something up their sleeve that we do not know about, that gives them hope of success in 2007. I have no idea what it is, but a sell out to an existing OTC company is one of the thoughts out of my speculative mind.
A buddy of mine did a similar thing 3 years back took about 2 years to found a small chip company complete with manufacturing set up, with zero debt. at the end of 2 years they sold their company to Nvidia. He and his 2 founders now work for Nvidia. They got funded by Venture capital, not by pinkie dilution.
After reading several replies to posters who emailed and spoke to Clint, Nick, IR and others, the impression I get is they are NOT CONCERNED about the pps, but are extemely confident of the company delivering its products on time and executing its plans to precise timelines. I too had a few emails from the company to verify the above.
