Here's a quote from someone who talked to Mr Chu,
Post# of 1140
"I took the time to call Chris and talk to him about this last week. He told me that the MS5 and MS7 milestone dates were estimates, and that the company had to have reliable repeatability and be able to achieve these goals consistently and on a mass production level before announcing accomplishment, which makes sense to me. He also told me that he made management aware that anything past 4 weeks without an update is what would be considered unacceptable to the market regarding the due date on milestones as we would be a third of the way through Q4. I was reassured that a PR would be issued before that time to update the market on these milestones. I can live with that, as I am in this for the long haul and understand that disruptive technology takes time."
