It just does not make sense and there is no explanation to why. How can a company afford that? When you sell something for 599$ and then later buy back the same thing for the same price which nobody wants to buy any more because there is also the other thing (jalapeno) that's way faster and way cheaper than the original ... you are not going to sell it again.
It sounds a lot like the "establishing trust" in a Ponzi scheme. let's take the numbers to see which magnitude we have here with the old system (599$/832MHashes) i would get less than 1.4 MHashes per Dollar with the new system (1299$/40GHashes) i would get more than 20.7 MHashes per Dollar that's an increase of 1478% with the upgrade (699$/39168MHases) i'd even get 56 MHashes per Dollar that's an increase of 4002%
