We need more miners too, but they will come if the price goes up. As of now it is actually profitable to mine and sell at 0.00000200.
And when winter come because it is too expensive to mine scrypt coins now and cooling the cards with air conditioning.
One of my 280x cards have been running on 95C for a month now. It goes down to 85C at night.
I live in Norway so I don't have air-condition, as it's not very common here. It's pretty cold here most of the year.
