That's been out for a while now:
https://downloadcenter.intel.com/download/27337/Linux-Processor-Microcode-Data-File

so I really don't think this is an "update" yet.

I saw a bios update for my Dell laptop dated December 28, but it didn't
seem to change anything with the cpuids or microcode status from before.

A hard answer to what "soon" means here would be nice to get, as I'm
seeing a lot of misunderstanding floating around right now :(
