I read up a bit on this. Apparently the beta BIOSes could have support for it but it's not guaranteed to work.

It was interesting, as no one knows whether the X470 mobos would be able to support PCIe 4 reliably, we already have the TDP increase that 4.0 requires, how are the old motherboards going to do it at half the power draw? All X570 support PCIe 4, it's part of the spec. The question you're asking is how many PCIe 4.0 slots and how many bonded lanes.
An interesting table:

X570 drops support for 1st gen.
My question is why do you need pcie4? If it's something you need for nvme raid etc then cool pay the price, for the vast majority of destop users and gamers it's simply not needed and a b450 will do the job.
The new RX 5700 is PCIe 4.

Planning to add some Nvme drives, yes, and hoping within the next two years to move to a 10Gbps home network, already got the cabling sorted, but shouldn't be an issue unless graphics and network and storage run full speed at the same time (which should be near never case).
The main reason is that I already see Nvme drives that can saturate PCIe 3 x4 link (4GB/s, and pretty much all M.2 slots are x4 links), and hoping prices come down a bit more.
I mean a "cheap" drive like: https://www.wootware.co.za/mushkin-...e-m-2-2280-pcie-3-0-x4-solid-state-drive.html can hit near 3GB/s already, so will be interesting to see what the next year or two holds.
The price difference was "cheap (R3400)", so went with it. Could have saved a thousand and gone with a B450 board instead, but I wanted to have the option of later upgrading to a 3900X when the 4000 series come out, since at that time I should probably have finished/come close to finishing up my studies and have a stable income, by that time R1k won't really mean much to me.
(Hoping it will drop to ~R6-7k by then, but let's see what the future holds)
EDIT:
And in regards to why not 10Gbps on the board already, well that's since there's pretty much only one board at that price: https://www.wootware.co.za/msi-mpg-...d-am4-x570-atx-desktop-motherboard-29831.html and if I want to pay that much, I'd rather set up fiber and get a ~$100 RJ45/SFP+ card. Think if you get second hand you can get them ~R1k mark. Prices have been falling a lot over the last year, especially thanks to Mikrotik.
/EDIT
It supports PCIe 4, but doesn't matter, since it doesn't saturate the PCIe 3 x16 slot.

Where? It's the first time I'm saying it. But seeing as the AM4 platform can last you 5 years, it's already 2 years old, wouldn't you want something that's a bit future proof? Seeing there are already 4.0 devices...
So what are you going to do with this PC?
No it's the second time I can recall. I still don't get it, pcie3 is nowhere near saturation and the am4 platform will probably be superseded by am5 or whatever they gonna call it before it becomes an issue. pcie4 has a very niche target market right now and for some time into the future.

I have a few different plans, going to use it for video rendering, run some big data stuff (which is why I know I can max out the Nvme drives), gaming, then probably media share as I have 6TB of HDD already hooked up in it before now adding an M2 ssd.
