HashFast, Cointerra, KnC pending...
they will have 28nm chips.
Bitfury still only 50% of KnC power draw

and already delivering
Bitfury at wall is around 1W/GH
KnC Max at wall is 1.6W/GH
Somehow I'm not seeing the 50%

Would you prefer a 400GHs by Bitfury delivered in a week or a 400GHs by KnC early October?
That is the question my friend...
