That's kind of sad. I mean honestly, I was not looking forward to Comet Lake 10c since it would come with some ugly compromises, but at the same time, Intel should be trying to launch that chip this year and then Rocket Lake next year, on the desktop. Too bad Rocket Lake hasn't actually shown up on any desktop roadmaps yet! But if Intel wants to "go agile" and pull another 8700k or 9900k-like stopgap move, the one to pull is 14nm++(+?) Rocket Lake.
Probably not. Realistically speaking, you are not going to get a 9900KS running faster than 5 GHz unless you want to push past 210W. Maybe in a gaming workload, it can keep power usage kind of low, but that will more-likely-than-not be in GPU-limited scenarios.
In any case, the 3800x is supposed to be able to match the 9900k (PL1, 160-165W) in everything, including games, and do this with its stock TDP limitation of 105W. Put the 3800x in the same power envelope and the 9900KS will lose.
I find it highly unlikely that anyone will be able to run a 9900KS @ 5.3 GHz with only ~170W of power consumption.
10c Comet Lake is/was supposed to be a chip for enthusiasts/overclockers. It was going to be Intel's "Zen2 killer" according to some bombastic Forbes article released months ago. Hmm, let' see if I can find it. Oh, here it is!:

Anyway Comet Lake would have been maybe 10c/20t @ 5 GHz of 14nm madness. But instead we get some overbinned 9900K? Okay.
