Don't know if they officially announced anything (probably not), but it's listed on their Genoa slides. Zen3's uArch changes seem to be moving towards supporting AVX-512, and the Gigabyte leak provides a bunch of info on the topic.
With all the other rumoured info, at this point, it'd be more surprising if it were missing.

13th gen still uses Gracemont, so unlikely to support AVX-512. 14th gen is using something different, so who knows.
Intel doesn't appear to be dropping it on their server SKUs, so it's likely the P-cores would retain the feature (even if fused off on consumer SKUs), and AMD likely have little reason to drop support (unless their own Zen4c cores do something, but they've already claimed ISA parity with Zen4).

Really, the only limiting factor now with AVX-512 is the Atom cores. Of course, overall adoption will take time.
