The AMD RX Vega already have the confirmed prices for the United States and Europe, being very similar to the NVIDIA GTX 1080, so it is possible that the miners will get them before the gamers.
The price of the AMD RX Vega is an important element and one that has been talked about a lot in recent weeks, initially setting ridiculous prices by some Swedish media, all due to erroneous information from wholesalers, although they were given certain validity by other means, which published other similar prices. This is now over, as the final prices for these graphics cards have been leaked in the American markets.
The RX Vega 64 Black (stock heatsink similar to the RX 480), has an MSRP price of $ 499, while in ShopBlt in the United States, it will have a retail price of $ 650 and the price in Europe will be $ 599. The RX Vega 64 Limited Edition, which was priced at $ 599 MSRP, will go on sale on ShopBlt for $ 650, while in Europe it will be priced the same as the Black at € 599. Finally, the Liquid Edition model has an MSRP price of $ 699, while in ShopBlt it will be sold for $ 758 and in Europe this graphics card will be priced at € 699.
It should be noted that the NVIDIA GTX 1080 with a custom heatsink by each manufacturer are for around € 600, some models below that price and with a little overclocking from the factory. In the end, the high consumption and performance similar to the GTX 1080, at this price, put it in a difficult situation. Even more so if we remember that Gigabyte recommends a 750W power supply for the Vega 64 Black and Limited Edition and a 1000W power supply for the Liquid Edition, with which we must add about € 20 more to the budget, which makes the system more expensive. .

So, will the 1070s be priced lower? And is there any news on when the RX580s will be back in regular stock?
The GTX 1070 will not drop in price, that's for sure. We will see if the price will be store or wholesaler. There will never be a stock of the RX 580 and if there is, it will last less than nothing.
Won't they drop in price when VEGA 56 comes out?
I doubt it horrors
Fixed that they lower them
I also think they will lower them
Stock of 580, probably when they begin to satisfy the demand of the miners of Vega and stop buying polaris, calculate at least 6 months
I would settle for the 1070 to be at their normal price ………….
