100% SCAM....after KnC, Butterfly labs and etc. who the fuck will purchase a miner (rendered wtf) from chinese site
Lketc is part-owner of bw.com - doubtfull this is a scam with the track record Lketc has.
The one quote I've seen so far on price was "0.76 BTC per TH" - nowhere near the $500/TH that the OP mentions.
At $500/TH this would not be a competative design at all, with ZERO chance of achieving RoI even on very cheap electric.
I have seen 0.76 BTC/T but only in relation to their B-Eleven Hash Investment program.

Have not seen anything in relation to a Miner purchase and would be very surprised if any prices had bee released yet?
51ASIC from the OP's post just seems to have a speculative (Scam?) announcement.
Very soon !
