This is criminal marketing at it's finest. There is no hardware that supports this standard. Cameras will need new chips to support this so it will be a few years at least until we see the standard supported. So this is of no benefit to users other than if they also released a new card reader sop you could download images faster.

False, three cameras have this standard already! Sony A7000 , Nikon D990 and Canon R2

They will also be used on cameras , (based on leaks) such as the Sony A7R VI , Sony A1 II , Nikon Z3 , Nikon Z1 and Canon R1 and Canon R3 Mark II

Thanks for the utterly clueless comment using imaginary cameras. There is no current camera on earth that supports CF-E 4.0 standard.

For cards that record raw streams, access time and writing speed are much more important.

8k@60fps in 36-bit color with 4:4:4 encoding (i.e. without loss in color and resolution) requires a recording speed of 9 GB/s, i.e. This is almost the peak performance of a pci-e 5.0 ssd for reading, not writing.

To record a compressed signal, even at 12k@120Hz, the stream in H265 and especially H266 is an order of magnitude smaller and less than 1GB/s.

For cards/ssds and nand in general, data safety over a long period of time is now much more important - at least 15 years. You never know for some reason that important files ended up on the card or ssd for such a long time... and 3D tlc has big problems with this, as well as with the recording speed.
