A quick blurb article from Engadget last Wednesday shared an announcement from PCI-SIG: PCIe 4.0 is coming, and soon (release is projected for 2015). While the information that's been shared on the evolved PCIe could fit onto a single notecard, full specs are expected to be available in 2014. Check the Engadget link for the full announcement and get ready to upgrade your motherboards (in 3 years).
Just in case PCIe 3.0 wasn't fast enough for you.
