Unless there is a huge surprise on the horizon, the next console generation won't have anything to do with real-time raytracing, which means AAA games will still target the current pipeline for quite a while. Sure, we'll have a RTX switch with better shadows and another gimmicks in selected titles, but the new technology really asks for games and game engines specifically made for it, and that's not going to happen anytime soon.
So, what's the value proposition here? Despite a long presentation and a massive marketing campaign, zero information was given about real-world performance in current titles compared to the previous generation, which essentially guarantees the comparison is not favorable to nVidia. With 4K displays starting to become commonplace, the thing customers really need right now is a faster, more affordable GPU which can bring the 4K/60 fps to the common gamer. This announcement went the opposite way: expensive cards with dubious performance improvements and a completely new, alien technology which doesn't really translate to anything impressive on screen (judging by the presentation). This is not what anybody wanted and, despite nVidia saying they know better, this is not what anybody needs.
In addition, the huge focus on general computing tasks on this presentation makes me think the new cards are going to be stellar for cryptomining. It's likely that coins that are currently somewhat resistant to GPU mining are going to fit much better those new Turing cores. If this confirms to be true, we'll face yet another speculation bullshit craze, and the prices can go even higher.
