It's not clear if the fixes will be revisions of current generation Kaby Lake, Coffee Lake, and Skylake parts, or if the modifications will be constrained to the Cannon Lake processors that are expected to ship this year. Nor is it clear what form the fix will take: better, higher-performance versions of the microcode and workarounds already being rolled out, or deeper modifications to the processor's speculative execution and branch prediction behavior.
