It would be pretty amazing if Knc switched directions and starting selling in stock hardware that ships immediately for a reasonable price.
I would buy a Neptune right now if it was ~$1/GH and shipped immediately, but their current batch 3 pricing is a joke (~$2/GH with an unspecified shipping date).
The Neptune is very competitive from a performance standpoint with other hardware on the market, and they would sell like hotcakes if they were priced competitively and sold from stock like Bitmain.
