Impact of Bitmain’s Upcoming ASIC Ethereum miners on mining difficulty going up and mainly Ethereum Prices[DISCUSSION]

The title pretty much says it all, I want to hear your opinions on the impact of ASIC miners on the price of Ethereum.

I mean technically, it shouldn't have much impact on the prices because the number of ether that can be mined per year is locked and so supply shouldn't increase and as long as the Demand Keeps up the price shouldn't fall.

So what are your opinions.
