August is a long ways off, are we likely to see any sort of performance increases or optimizations beyond the expected 5.4th on the SP30?  Is that just a low ball estimate of power and it'll end up being faster, or is that a best case scenario?  With the orbital death-ray of KNC and BFL shipping before August arrives we're likely to see the difficulty rate jump up significantly before you ship.  We know BFL has more than 20,000 Monarchs to ship out and however much that purchased hosting contracts.  Also Black Arrow ships in two weeks, and Asicminer has boards in hands testing right now.  So the difficulty is about to explode.  Trying to view this from that angle and think about what 5.4th will really return by August.  Are you able to ship sooner than August if everything goes well?  Any sort of other perk to this process that makes investing the money to buy something so late worthwhile at this point?
