I've held off buying more XQD cards (one came with my D500) so this is good news as I can use CFexpress across multiple bodies. About time!

CFexpress cards use an interface called PCIe 3.0, as well as NVMe 1.3 protocols.
CFexpress card Type B cards can theoretically reach 2,000MB/s. They are physically the same size as, and pin-for-pin identical to, another card type – XQD.
The fast cards enable cameras to be capable of greater RAW sensor output, higher frame rates, and higher resolutions. It’s up to you when it makes sense budget-wise to upgrade.

How exactly faster cards enable higher resolution or greater RAW sensor output (whatever that means) ???
Buffer speed, sure but higher frame rates ???

Having a faster card will support larger files and be quicker when processing them. The simple answer is speed. When the write speed limit of your card is greater or equal to the speed limit of your camera, the camera operates at its maximum performance. It will shoot at its highest frame rate until the internal buffer gets full and then slows down while offload to memory which lets you get back to full speed the fastest.

Right but it won't magically make camera take pictures at higher frame rate. Whatever the fastest frame rate is that your camera
is capable of you can't make it faster no matter what card you use. I thought that would be obvious.

I am sure with "enable", he meant "enable future camera designs to have greater..."

I just did the firmware updates for my D500 and D850.
I did see this notice on Thom Hogan's website that makes me wonder about this new card type for my D500 and D850.
"Nikon has finally introduced the long-awaited firmware updates for the D500, D850, and D5 cameras that support CFexpress cards (and fix a few bugs). Just a reminder: don't expect speed increases, as the card slot mechanisms in these cameras has a fixed upper limit that dates to early XQD. Some D500 owners need to perform the update twice (pay attention to the instructions on Nikon's download page)."
Does Thom's statement refer only to the CFexpress Read speeds or to the Write speeds, or both in a D500 of D850?
Any recommendation for a CFexpress card reader? (I am assuming that my Sony XQD card reader will not work for this new card type.)

Exactly.
Thanks, EJ!
