The disposable income varies among countries though. E.g. in Germany inflation exists as well, but last year the minimum wage was increased by more than 10% (without the economy crashing, and with jobs still available), and rents are way lower than e.g. in London. So here I sit in Berlin, with an income below the local median, and I am like: "Wait, what? 3nm-based GPUs are not in production already? Lame! First these companies get me all hyped about the newest technology and stuff, and now all they want to sell me is like some last-gen pen and paper? What a let-down!".
I mean, e.g. a 4090 would be quite an expense for me. But because it is just an expense, I can not afford to purchase such a GPU every year, and why then go for some technologically last-gen stuff?
Joking aside though, I think what the GPU makers have been somewhat overestimating is the interest for 4K gaming. Many gamers do not want that, or do not care about it, or simply upscale (as consoles do), possibly thinking that they have full 4K already. And in such a context, offering a 4-nm based GPU primarily designed for 1080p gaming, and one for 1440p, and reasonably priced of course, that may arguably drive sales a bit more than just trying to sell what is way over the top for many a gamer.
