Since Intel dominates the CPU OEM market and their CPUs are still favored by most people building their own desktops, Intel does not really need to do anything at the moment. If the CPU performance is better than expected, then maybe... maybe Intel will drop the MSRP for all desktop CPUs by $5. But that is unlikely.
Coffee Lake is expected to be released in the 1st half of 2018 (unless there are delays). It is rumored to bring 6 core Intel CPUs to the "mainstream" and will be based on the Kaby Lake CPUs, not the upcoming Connonlake CPUs later this year. Will these new 6 core "mainstream" CPU be more expensive than 6 / 8 core Zen CPU? I would be surprised if they will not be more expensive.
