A full on integrated chip is in the range of $50 million. If enough proof points are achieved for various suiters then, yes, multiple NREs are possible. By September? Possible. For the last two years I have suggested that a product will be ready for market entry come September of 2016. If that becomes reality, I expect NRE's prior. Regards. Derekwpg
