Sounds like Intel has solved 10nm and is confident it'll release on desktop this year.
PREVIOUS (incorrect): You can buy them (the "Rocket Lake S" platform) beginning March 30th, I believe. One issue they are having with 10nm (though not intently a fatal one) is that it doesn't seem to achieve market-leading single-thread performance without being ridiculously power-inefficient. In lower-power environments, e.g. in laptops, the 10nm chips seem to be "fine", in that they are improvements over 14nm+++. They're still not market-leading, but they are an improvement and not at the cost of power (relative to previous generation).
