Or
20-35 9if july/august
Well, frankly: there is a huge difference between 30BTC or 40BTC
Even greater between 20BTC and 35BTC
40BTC seems too much for a 45GHs unit, even if it's delivered in June (we all know it will most likely delivered in July, if everything goes well). 30BTC would be OK IMO, but 25BTC would be really great and would attract a lot of customers which are now thinking on BFL
35BTC for July/August would be crazy IMO, the difficulty will be at least x5 what we have now. 20BTC for August? That would be nice.
