It's also expected to cut costs, as odd as that sounds. In the same way that shifting to a smaller manufacturing process for CPUs and GPUs can help cut costs by reducing component waste and helping systems run more efficiently, moving to a quicker expansion slot speed means manufacturers can use fewer data links or assign more tasks to each one, cutting down the total cost dramatically.
PCI Express 4.0 to double bandwidth to 64GB/s

Tom's Hardware writes the PCI Express 4.0 specification is getting a step closer to introduction. Hardware companies are drafting the new standard, which will enable a base speed of 16Gbps per data link, resulting in a bandwidth of 64GB/s for a 16 lane port. Besides doubling the bandwidth for high-end applications, PCIe 4.0 also promises to cut costs.
