The following assumes local pick-up.
Given a 15% increase projection (the next diff is likely to be in the 25% range) the buyer will take a 3.6 BTC loss.
It has to be a 10% difficulty average for break even (maybe 8% or 9% since we're front-loading with a big diff soon)
The buyer will need a minimum of 17,000 watts of power and a minimum of $2,350 in supporting infrastructure and hardware.
If the plan is to upgrade to S3 blades, the price difference between an S3 and S1-upgrade-blades is $66 with delivery near end of September.
