Nanosys did not replace him..they were always there..who cares about your predictions...save it for ihub where the sky is falling.If hes changed his schedule then its probably for a good reason.If you owned a business you would understand that you arrange your schedule and if more important matters are pressing or come up in between then you attend the matters that affect you the most.There was no subject matter for his speech so perhaps he left it open depending on what is ongoing.Apparently there is someone who is inboxing people saying the company is going down...typical bs from these same individuals.I never understand people who had a chance to sell on the latest run and are still bitching and whining...no one is telling anyone they have to hold the stock or buy it..every stock is a gamble.
