Current Steam user survey results (now that the over-counting issue has been fixed) shows the GTX 1060 as the single most popular GPU installed by active Steam users with a 12.5% market share, the GTX 1050 Ti and 1050 take second and third place with ~9.5% and ~6% respectively that means about 30% of Steam users have a current-gen GPU in the $200-300 price range.
So yes, volume != profit, but the consumer obviously trends towards more reasonably priced cards. Cards in the Titan price-point that NVidia is trying to sell the RTX 2080 Ti at are so uncommon that they get lumped into the 'other' category of the Steam survey - and since I highly doubt magic like doing integer operations in tandem with FP32 operations is going to bring that much of a performance improvement to the majority of gaming workloads in tandem with the really weak raw numbers of the just-announced cards (fewer TFLOPS on the 2080 than the 1080 Ti selling in the same price bracket) it's obvious Nvidia is really taking the piss with their pricing. You're paying more for raytracing, that's it - and while it's certainly a cool feature I don't really see gamers caring that much until it becomes usable at that $200-300 price point.
