and judging by some of these $30,000 gpu's built specifically for bit coin mining that put out forgot how many ghz (but it's alot), that people are preordering that release next month, thinking they'll be able to mine to their hearts content, and the current amount of mining farms constantly being upgraded with higher end gear, along with people pouring into bit coin mining because of the success of bit coin mining, I'd say we got 2 to 4 months tops to do something about the 21 million bit coin cap.
The amount of hardware and mining processing power of the entire network combined, has virtually NO influence whatsoever on the speed at which bitcoins will be mined.
So people can buy $30K ASIC renderfarms all they want, it won't cause bitcoins to be mined any faster. Only the people who do have expensive mining hardware, will
RELATIVELY mine more coins than people who don't. But the rate of 50 BTC per 10 minutes (soon to be reduced to 25 BTC per 10 mins) remains constant.
