This press release would seem to indicate that PDSG is not being sold within the 120 day window. Indeed, it may be a signal that the tech is good and they have been advised to stay the course and promote it. I suppose it may also be an opportunity to further showcase the product and gather the attention of prospective buyers. Either way, participation in the show indicates to me, that after a prolonged silence, PTSC still has confidence in the market potential. good luck
