Sounds stupid, but still thinking about the last financing conditions...contradictory, but I certainly carry on hoping now that the ability to raise funds is not an indicator - in the special case of PTK - of where they stand in terms of technological advancements, in particular with partners.
NDAs and secretive (to public/retail shareholders) developments usually can not stop potential partners/investors to show their interest, especially as any breakthrough technology always requires large amount of cash injections.
Waiting for prototypes for a de facto revaluation of the share price.
