Our promise to our customers is that we'll deliver the most efficient chip and will practice a minimal profit.
At the time of the actual shipment we'll make sure that we sell our chip at the market price or lower. All pre-orders will benefit of the same discount by the time that we start shipping.
Customers who pre-order and pay now have 25% discount. Our promise is that we will ensure that customers who preorder now will always get a better deal than customers who order later.
Everybody until now sold you hardware that they knew that you're going to loose money because 1 month later they announced something faster at a better price.
We are guaranteeing that this won't happen with us: If we drop the price you'll get even faster hardware, keeping you in front of everybody else.
Yes, you are guaranteed to get a price 25% below the market price ($/ghash) at the time of shipment.
And yes, we will keep our prices below every other company.
What we are trying to say is:
- We do not know what will happen with Bitcoin difficulty/revenue in February or December or even tomorrow. We do not avoid questions. We do not have an answer. Nobody has. On that date in February we will sell cheaper than our competition. This is our promise. If products from competition will have ROI in February than our products will have as well.
Hope this statement is more clear.

The above quotes simplify to this for me: BlackArrow has promised his Prospero ASIC pre-orders (completely paid by Oct sometime) will be 25% cheaper than the market price of currently-shipping non-pre-orders of any vendor's comparable product at the time the Prospero pre-orders can be shipped. His currently-good reputation guarantees it. It is likely (assuming current trends) to not have much ROI if any, but at least we get a 25% discount on the best going price in late February and we get to become part of the mining elite helping bitcoin be more difficult to attack.
