Ever since reading the EVGA comment about a bios update coming for the X79, I've been checking the download page regularly and the last update is from 2017.  
Anyone have any info on this?

This is our current schedule for BIOS updates related to these vulnerabilities:
By end of this week*:  Z170, Z270, Z370, X99, X299, Laptops.
Within 1-2 weeks*:  X79, W888, Z87, Z97.
*Please note that this date is projected, contingent on receiving source code from Intel, and final testing may push the dates back temporarily.
At this point, we do not have source code from Intel to update X58, P67, or Z77 motherboards.  When/if that becomes available, I'll provide an update.

I believe the update was delayed for a bit.

It should be on the way.  Intel released and certified the microcode updates as in production on March 6th.  Search Intel Microcode Revision Guidance for details.  Now EVGA just has to create a BIOS using both the Sandy Bridge and Ivy Bridge microcode updates and release it.  Prior to that they were in beta under an NDA.  If I had to guess I would say we will have a new BIOS in a week or two from Tuesday at most.  If anyone from EVGA is reading this I'm sure that everyone who is waiting for a new BIOS would appreciate an update on the release schedule.
