"...no one has any idea of finished product..."  - hmmm, what is...

"...no one has any idea of finished product..."  - hmmm, what is it with all the dubious posts from some people lately, weird.

"Finished product" - we have a pretty good idea about form factor, weight, design elements/components, frequency response (for original design), reliability, power usage relative to traditional tech, method of sound reconstruction, potential sound quality, etc, etc.

"Production costs" - somewhere between a few dollars and $10.

"Margins" - see previous post regarding higher end estimates of potential margin.  Looking at other MEMS devices an extreme low end case margin would be 20%.

"Revenue will flow" - after they've finalised the design, obviously. According to the latest quarterly there's the potential for some inventory to be produced this quarter.

DYOR of course.
