Back in June of 2019, the PCI-SIG announced that work had started on PCIe 6.0 and some two years and four months later, PCIe 6.0 has reached version 0.9, which equals draft spec. What this means is that companies can now start to implement PCIe 6.0 into their products, to make sure they're compliant with the draft spec, since no additional functional changes will be made, unless something major is discovered.

PCIe 6.0 will be the first PCIe standard to use PAM-4 encoding, something it shares with GDDR6 memory among other standards. What this means is that twice the data can be sent per clock cycle for 64GT/s, or twice that of PCIe 5.0. Another key feature is FEC or low-latency forward error correction, as this was implemented to maintain data integrity. PCIe 6.0 is expected to be backwards compatible with all previous versions of PCIe. The final PCIe 6.0 spec isn't likely to be finalised until early next year, based on previous standards, although the original plan was to finish ratifying the spec this year.

PCIe standards come out faster then new iphones. Pointless for gpu's and i guess it serves the upcoming 5000$ ssd market?!

PCIe & SSD write speeds are going up all the time.
Meanwhile, flash memory archtecture (SLC->MLC->TLC->QLC->PLC->) and write endurance are going down all the time.
We will maybe see soon SSD:s that can be written dead in a single day...

I see your point but that isn't totally true, we got some good lasting SSD's from the CHIA fiasco.
What happens is that it's increasingly difficult to know what ssd's are worth it, especially if you don't follow tech every day.

the oddity with PCI-E is the 7 year gap between Gen 3.0 and Gen 4.0. There was probably nothing to push the standard forward and the GPU requirement was probably not enough.

But today, with the rise of PCI-E/NVME SSD, this have change and the demand is back again for more I/O bandwidth. This will also increase with things like DirectStorage and higher memory bandwidth with DDR5 and beyond.

Time to market? Make a guess.

Make a poll just to guess @TheLostSwede :p

I'm guessing Q2 2023

Think of it that I/O devices can benefit, where more (e.g. USB, SATA, etc) can be used with less lanes.
