From Intel we have what many speculate was a binned Xeon P 8180 displayed . The processor was running on a custom motherboard in the LGA3647 socket. It was cooled by a water chiller and ran 5GHz on all cores for a cinebench run. It will launch in Q4 2018.
We know nothing further on the specs of the CPU, but the final product is more likely than not a Cascade Lake X part running on the X499 platform.
Definitely easier to predict the AMD prices.
Intel can get away with charging more due to higher clocks, optane and AVX512, but charging twice of what the competition does has not done so well on X299.
IIRC AMD was pricier than Intel back in the Athlon 64 days, when they were actually faster. Then Dell, etc. Rest is history. I know I saw an article about it (maybe 2003?) but having trouble finding now.
The 8180 sells for 10k, the 8176 for 8.7K. Intel will not have these cannibalize the top dog Xeons, they are experts at product segmentation.
There would be little point for them to try and sell consumer parts for over 5K. Might as well just get the Xeon then.
This was my thinking. I was a little surprised to see people thinking this is actually a thing that will be buyable, let along for anything as low as $3-4000. Intel will not let that happen, not with out cutting it into a total potato to please their server buyers.
