Which class of hardware?
Haven't heard much on the consumer side except that mobile cannon lake (10nm) isn't really an improvement. Typically this is the architecture that makes it in for S-class desktop chips. So a minor die shrink of Kaby/Coffee lake essentially. I'm guessing frequencies will be an issue, they had such a long run with Sky, Kaby, and Coffee that we got used to the high numbers, but it always takes them a bit to re-optimize on a new process node.
CascadeLake X is also an iteration of existing designs, but sticking with 14nm. Leaks show that it is still trailing Threadripper and Epyc chips by a small amount (and still pretty much costs the same we can assume)
Not really heard any news on 10nm making it in to anything significant, and all the above is late this year into next year. So, basically expect nothing new from Intel. Or a new architecture on 10nm/DDR5 sometime in 2022 (Or possibly 7nm if they just skip straight to that).
