Playing with KnC's order system I get this message:

Sam said recently that they will just manufacture and ship hundreds of units per day, so even if you are not in the "first 500" Jupiters you will get your units in September. He also said they are not producing "closed batches", just manufacturing and shipping sequentially following the order backlog. But it looks to me they are indeed making batches, as there are only 1,487 Jupiter left to be ordered in their system.
We have people in here that is very close to them. Does anybody knows how many TH/s are they planning to ship and deploy from September to December 2013?
This is crucial information in order to be able to calculate ROI.
