Rickthevet: Seems like step backward.  Don't really see any difference between the previous few. They are not sharing the number of companies  sampling and what time frame to expect order announcements.

Rick, this is not a company presentation for possible investors but a purely technical talk to a purely technical audience. Anything else would be regarded as advertising by this audience and would not go down well.

If there were any people in the audience who are interested in sampling or even samples, they could ask such questions in the Q&A session or approach the speaker directly.
