PCIe 4.0 is likely to be short lived given that PCIe 5.0 seems to be around the corner. On the AMD side where they already have 4.0, few care for it (I do though - just ordered a mobo and processor that use it) - 4.0 nvmes aren't faster for common use cases, and it mostly matters when going multi-gpu which is only seen in some professional use (and even then you can use a threadripper and just have a lot of 3.0 lanes). Then next ~year ryzen 5000 which will require a new socket seems likely to already support 5.0. I'm guessing Intel will just altogether skip 4.0.
