AB350 PRO4 to support Ryzen 3000?

Only A320 are not getting Zen 2 support. Or at least the is the infocthus far.

Thank you both for answers.

It's worth noting, after seeing Computex 2019 footage on the X570 lineup (all manufacturers) that it looks unlikely PCIe Gen 4 will be supported on first and second gen boards. This is not in any way official, just my own speculation but if every board released on the X570 chipset has active cooling on the chipset to facilitate PCIe 4.0 transfer speeds and heat dissipation then it stands to reason that the passively cooled X470 and below boards will not likely be able to handle the data throughput and additional heat generation. There has also been mention of the actual circuitry needing to meet standards.

Regardless, it shouldn't be an issue for most users as currently the only devices even able to benefit from the new standard are storage devices. It will be quite some time before GPUs even come close to seeing a benefit. The only benefit I could possibly see to a GPU is in multi GPU setups, Nvidia could for example lower the PCIe lane requirement from x8 PCIe 3.0 to x4 PCIe 4.0 and allow SLI on lower end boards. Knowing Nvidia however, I doubt they will do so.

when the bios for ryzen 3k is rolling out? still nothing to see

isn't 3.31 for that?
