Max. order is 68000 apparently. Not sure if it is actually the current batch numbers or even a valid quantity. Still, that's amounts to a whole lotta wampum.
That would bring the network hashrate to 143 PH which is exactly 100 times the current. So profitability would be $4-5/day. Of course it would be insane to release 68000 at the same time, not to mention i don't think they have the production capacity. They haven't even shipped a single 16T miner yet..
