This is going to change in the future. The bigger hardware manufacturers like AMD and Intel are looking for new markets. If the market for Bitcoin or Crypto currency mining is big enough, they will expand their range of cards that are specifically targeted at mining. We might see these giants going head to head with Chinese ASIC manufacturers.

As mining gets cheaper in Russia and other countries with subsidized electricity, we might see a higher demand for ASIC's and these Chinese manufacturers might be pushed to manufacture more units or the competition might deliver on their failures.
