I'm getting concerned about that... I've designed a product around prices that were announced months ago and then rescinded, and I've been waiting approaching two weeks for $800 worth of chips that are "sorry they're expensive but they ship immediately" to be shipped.   My whole model depends on chips being available early in October and near the price I expect.  Bitfury chips are great, and I'm thrilled with them so far from a technical standpoint, but there's not enough margin in them if anything goes pear shaped :/
