The real reason NVidia are ramping up the price of GPU's is that the lower end of the market has evaporated, APU's are good enough now that you don't need a dedicated GPU for the average consumer. So this leaves NVidia, who cannot compete with APU's as they don't have a CPU license, with only the mid to high end in which to make money. It's also the reason that they were the first to diversify, a fail of AMD here not to do similar sooner, into things like AI/DL/cars.
The 2080 and 2080Ti won't be sold for too long, nothing like as long as the 1080's for sure, there isn't any reason for any rational person to upgrade from a 1080 to a 2080. There is no games that use ray-tracing out yet, and ray-tracing in games won't be viable until the next generation AT LEAST! The frame rate hit is too massive, hence the heavy usage of de-noising to clean up the images. AMD could have capitalised this time round but they are not even in the fight this time round which is a shame, but even when AMD/ATi had the fastest card they were still outsold by NVidia because of their dodgy tactics.
