A bit early to tell, but I think my first order of wafers is going to be 30 PetaHash = 30,000,000 GH, by the end of next year it certainly be in 1,000 PH range, god only know what Knc/Kcn will come up with
Well they will have to think of something, all that hashrate centralised to one owner will not be healthy for Bitcoin. Having all that hashrate located in one country, especially the US will definitely not be healthy to Bitcoin! All it would take is for yourself to be penalised by a government with an assumed valid reason and that could be 30 Petahash taken off line in one foul swoop.
I hope you are not seriously going to try and handle all that hashrate yourself, and in one undistributed location (even one country)...
