>8 cores at any frequency higher than what the 9900KS is already at is a pipe dream on 14nm regardless of how many +'s you add to the end of it.
I've got 0 interest in any CPU Intel can offer until they do a die shrink.
Cores isn't all that matters -- some of us really wished the KFC edition materialized. 9900K with 32MB, 64MB, or even 128MB of L3/L4 will outpace anything in the 8-10 or even 12 core area right now. There is still a gap to fill between 40ns (DDR4) and 10ns (L3), but this fruit definitely doesn't hang as low as it is with Ryzen 3000.
However, as Swan notes, “The short story is we learned from it, we'll get our 10nm node out this year. Our 7nm node will be out in two years and it will be a 2.0X scaling so back to the historical Moore's Law curve.”
