I guess his health problems might be the reason for the few shares he had to sell. I hope he will get well very soon. He should have the chance to enjoy his retirement. In my opinion this can only mean, that everything should be more or less done and proof and as he states he is very confident that POET will get it done now even without him. So even when it is a bid sad that he has to go, it also is very good news and shows how far POET is now. Would like to know more how to put the technical details into perspective.
