Intel is developing SoCs with PCIe 5.0 capabilities right now. Most of the corps have skipped 4.0 in favor of 5.0, and AMD is pretty much the main one using 4.0. Maybe NV will do something with it next year, but I doubt it. I think we'll get 5.0 with sunnycove or Zen 3, so around 2021. DDR5 should be ready around then as well.
On a mainstream level, 3.0 is enough, but that's today. PCIe 3.0 wasn't needed on X79 7-8 years ago, and look at how well it has held on. Whatever platform releases with DDR5 and PCIe 5.0 will be a good one to sit on, especially the HEDT version, if history repeats itself. Those two things are one of the biggest determiners of a platform's age. Now with low core counts being a thing of the past, and with workloads becoming more parallel and GPU bound, memory latency, memory throughput, and PCIe bandwidth will be a bigger deal than before. Well, that's my prediction.
