Clearly Bitmain is taking the piss... pre-order 3 months out and they raise the price.

But it could be good news for July batch buyers. Perhaps Bitmain will try to keep difficulty somewhat sane over the next few weeks now that they need to show some possibility of ROI for this September batch. It's starting to look like a very convoluted ponzi scheme where early buyers depend on latecomers to keep the demand up.
