AMD stated that the full EPYC stack will be available for top-tier OEMs end of July. You're unlikely to see them being sold at retail directly until the tier 1/2 OEMs have had the opportunity to take their fill for their customers. That will take a few quarters. Compare it to Intel - their top-tier partners had the hardware last November, but Intel announced 8 months after that. AMD launched its parts at the start of that 8 months, rather than the end. That's where some of the confusion about EPYC's availability lies. No-one complained they couldn't get SKL-SP back in November because no-one said anything: I'm guessing that AMD had had to make some announcement, given the delays, the projects, and to drive up OEM cooperation/customer anticipation (and show something to investors).
