I don't know where you got those numbers, but if that is an accurate schedule of Asicminer, we are pretty much fucked.
CoinTerra 2 PetaHashes by December, BitMine will bring 4 Petahashes by March, FastHash and KnCMiner who knows how much more.
CoinTerra and KnC are both already going full throttle using 28nm.
IF AsicMiner doesn't put their shit together bringing a couple of petahashes to the network, even 2 BTC per share will be overpriced.
There is no more reason to be holding back, being the most capitalized company in the bitcoin world, they should be leading this fierce competition.
Cointerra - doesn't have anything yet
BitMine - doesn't have anything yet
FastHash - doesn't have anything yet
KnCMiner - doesn't have anything yet
I don't know where is the informatino that CoinTerra and KnC are going full throttle using 28 nm, but I haven't seen proof of such a thing.
Asicminer has already experience with 130 nm chips and the new generation will be produced pretty soon afaik. You should walk before you start running.
Correct me if I'm wrong in anything
