Am I correct that if there is no announcement of PCIe 4.0 compatible components (CPU, GPU, motherboard) at CES 2018, there is a very very low chance that they will be available for consumers to make high end PC this year?

I mean ready as in finalized by the PCIe-SIG so device manufacturers can finalize their own 5.0 devices' design and get ready to launch stuff.

Put yourself in the device manufacturer's shoes: PCIe 3.0 has been around for five years, PCIe 4.0 don't have anything to plug into yet even if they existed and by the time the first servers with PCIe 4.0 launch, PCIe 5.0 may be less than a year away. Would you bother spending tens of millions in compliance testing equipment and R&D for a standard that still fails to deliver the bandwidth current high-bandwidth devices require (mainly NVMe SSDs) and will be obsolete after perhaps a year of production...

By "ready by the end of the year", do you mean available to purchase by the end of 2018?

I want to build a new system with possible multiple GPUs running at at least x16x16x16x16 for CUDA computations.

For many companies, it will make more sense to skip PCIe 4.0 altogether and focus on 5.0 instead.
