Well, 16 cores on mainstream and pci 4 basically doubling 3's lane count makes for a pretty good HEDT coffin. Hopefully it isn't true since HEDT platforms tend to last longer than the mainstream ones. It's most likely what bmgjet said. Demand is likely high for the epyc chips, navi is likely taking up some space in the fabs, and 7nm yields might not be as good as 12/14nm. I don't think HEDT is dead, it's just that Intel is behind schedule, and AMD is prioritizing what will grab the most marketshare. HEDT is likely on the bottom of that list.
