Known "secret" in the industry:
KNC won't ship Neptune in Q2. They'll get samples in July / August.
They've taped-out in the beginning March, 20nm cycle time takes 4-5 months.
Like other ASIC provider we won't disclose here, they've chosen the interim, problematic 20nm process.
20nm will be replaced by 16nm FinFET next year, for a good reason.

Ask for transparency. It's your money.
