Two roadmaps from Intel have leaked, and they show some interesting information. First up is are Comet lake based processors with up-to ten cores. Intel would be releasing these in 2020 and they are fabbed on a 14nm process.

The more interesting news is that in 2021 Rocket lake would make an introduction, and that's the first time that that name surfaces. It's also still listed as 14nm and shares the same amount of cores as Comet lake, indicating an improved or updated 14nm fabrication procedure. 

The roadmaps that derived from a Dell presentation share info on both mobile and desktop processors. It is not clear how old the roadmaps themselves are. If correct, there are no 10nm desktop processors on the Intel roadmap for the next two years

New Intel Roadmap leaks: 10 core Comet lake in 2020, Rocket Lake on 2021, both at 14nm
