PCI v5, when?

[nulik]

PCI-SIG is getting ready to release PCI v6 (64Gt/sec) by 2021...

But at this moment, I don't see any motherboard with PCI v5 (32GT/sec) available on the market.

Is there any PCI v5 motherboard out there? Which manufacturer and what model?
TIA

p.s.
just in case anybody would ask why do I need PCI v5 (or v6) , well it is not for games, it is for machine learning

There will be no motherboards with PCIe v.5 until sometime after the release of the standard. PCIe 4 is still wet behind the ears.
