With the present sales of ASIC chips in bulk from a competitor, Avalon, in lots of ten thousand to distributors, new miner units could reach retail customers by late July. If so this extra estimated 84 TH/s, at around $2.8 million in chip value, could have an enormous impact on mining output and difficulty levels thereafter.
Lets hope Butterfly Labs Inc. deliver as promised, and you are not one of the unlucky ones that will be mining just to cover their payment to Butterfly labs.
Good luck.
Ha! 49 Million on Sep 17...
