That's a little weird. A new chipset is here and they're reviewing the previous gen. Cuckoo...
LOL, they have a whole section on it:
Final edit: The reason Two there is BS. Not only a lot of good features of new gen CPUs are not supported by the 3XX chipset, the overall firmware update experience is not very good (from complaints I've read).
It works, but it clearly is not ideal and you're not getting the "by design" performance from the new CPUs, which pretty much defeats the whole CPU-update-only idea (disregarding the APUs). Sure, they will clock a bit higher still, but if you have money to throw, why not update the motherboard as well?
If anyone is buying a new Ryzen 2XXX CPU, there is totally no reason whatsoever to go and buy the 3XX series board. Lol, you wouldn't be able to use it right away either, because it needs a firmware update.
