CFexpress 4.0 has been announced and the only real changes are in the NVME spec that has been bumped to 1.4, to give greater efficiency, though the NVME spec used in CFexpress is still behind the latest (2.X) used by SSDs, due to the feature upgrades having no real use with rewriteable flash media used by cameras and other such devices. No camera bodies are expected to incorporate it until 2025, at the earliest, as the existing card and device host controller designs have to be upgraded and tested together, before they can be certified and brought to market. As intended, the new cards and cameras will be backwards compatible with the current cards and cameras that are using the current CFexpress standard.
