In June 2017, PCI-SIG preliminarily announced the PCI Express 5.0 specification.[50] Bandwidth is expected to increase to 32 GT/s, yielding 128 GB/s in full duplex networking configurations. It is expected to be standardized in 2019.

That's partly because the memory controllers in processors and SoCs need to be updated to support DDR5, and these chips normally take two or three years to design from start to finish. DDR4 RAM was finalized in 2012, but it didn't begin to go mainstream until 2015 when consumer processors from Intel and others added support for it.

AMD last year stated don't expect PCIe v4.0 on their CPU's until 2020.

Taiwanese mobo makers don't have your shiny object/squirrel issues.

Yup. Aside from HPC and ultra-high bandwidth I/O, what needs it? I could maybe see a case being made for GPUs, but even that is iffy, given that anything bandwidth intensive is done using the GPU's onboard RAM these days.

Sure, but PCIe has nothing to do with iGPUs, and memory bandwidth for iGPUs is always going to be constrained since CPUs with iGPUs tend to have single/dual channel memory at most.
