PCIe 4.0 will be finalised this year, PCIe 5.0 is planned for Q1 2019

 
The PCIe 3.0 standard has been here for quite some time, releasing on motherboards as early as 2010, offering levels of bandwidth that was more than adequate until fairly recently. 
 
Now with the release of PCIe NVMe storage products, Intel's Optane Storage, faster networking solutions and the growth of the GPU Compute/AI markets PCIe bandwidth has become a limiting factor, bringing forward a need for an updated standard that will offer the bandwidth that the industry needs. 

 
PCI-SIG has announced that the PCIe 4.0 standard will be finalised this year and that the organisation plans on accelerating the development of future standards, with plans to finalise PCIe 5.0 in Q1 2019, focusing primarily on pure speed increased rather than other feature updates. PCIe 4.0 will offer 2x the bandwidth of PCIe 3.0 while PCIe 5.0 will offer 4x the bandwidth.  

Some IP vendors are so eager to adopt PCIe 4.0 that controllers for the standard already exist, albeit using the incomplete 0.9 standards.

While PCIe 3.0 remains more than adequate for the needs of consumers today, this will likely change in the future as NVMe SSDs, Optane system accelerators or more bandwidth hungry GPUs come to market. At a minimum, it will allow consumers to do what they do today with less memory bandwidth, as PCIe 5.0 4x lanes will offer the same bandwidth as a full PCIe 3.0 16x lane configuration.

We are headed into a future where everything will use PCIE bandwidth. Even your hard drives. We're going to need it Quote
