They could sell them all for $7K each right now if they started taking pre-orders tomorrow for early January delivery. $2K would be nice tho and especially if they only sold them to return customers. HF and CT are both only promising to ship by the end of March if you pay now.
If they went for $7K each then I would have to agree with Meizirkki about their smugness. Customers should get the benefit. So we can buy more KnC in the future if still viable to do so.
They're a business not a fan club if they was to only charge $2K per >650GH/s machine then it work out cheaper than buying a Neptune. IMO $5K is the lower range of my estimate.
