The fine wine thing was debunked 480/580 etc (check out Hardware Unboxed video), Do you know why the 570/580/590 and V56 (V56 prob makes a loss and polaris not much profit I bet)are so cheap and much more competitive. Competition the prices of thouse cards dropped hard when the 1660ti/1660 got released.
I'm still waiting 2 years later for a alternative to my 1080ti at the same or similar price point (£600-£800) and the best AMD almost 2 years later was the VII, same price , smaller process, more power! Not Stella competition, so while I hate that nvidia jacked up the price of the 2080ti I don't blame them as there a business after all.
Competition has proved time and time again to improve products and prices, no weak completion leads to not weak products and bad pricing.
Lots of people like me with 1080's 1080ti's etc will prob have to wait till 2020/2021 for a upgrade path at the same/similar price when Xe hits and hopefully brings some competition
ps the Vega launch prices of $399/499 where BS as you know with the whole launch day rebate BS.
TLDR: AMD need to really up there game if they want to make a profit and take back some market share with there GPU's, they need a Ryzen but for there GPU's and Navi is unlikely to be it.
