Where are they? Anyone have any details on plans? I don't wanna buy into the rumors that it'll be passed over for 5.0, and I don't want to get stuck on 3.0 like I did when I bought my 2600k and and PCIe 2.0.

I'm having no hope for Zen+ boards to supporting this, so we'll be waiting for another year?

So disappointed right now.

last I heard Intel and AMD aren't supporting it until at least late 2019.

Unfortunately all I've seen as well are signs pointing to 2019. i.e. Ryzen 3xxx, Navi, blah.

I don't believe I'm alone with holding out on a large investment system upgrade when these are apparently not that far off. I just hope this doesn't keep dragging out and as the standard was progressively refined over the years, I find it disappointing to have a 1.5 - 2 year gap in product releases.

Nothing really for the next 5 years. It takes 2 Titan cards using the Vulkan API in Ashes of the Singularity to come close to maxing out the PCI-E 3.0 spec. With PCI-E 5 on the horizon we won’t be seeing any GPU’s coming close to maxing out that bandwidth for at least 5 years. The only potential place to exploitation is RAID0 NVMe SSDs. Even then they are very pricey.
