It looks like the Canon EOS R5 Mark II will continue with the 5 series lineage and keep the fast card/SD card memory card configuration. So we'll get a CFexpress Type B slot along with a UHS-II SD card slot.
Starting with the Canon EOS 5D Mark III, Canon has used this configuration in all of their 5 series cameras.
We know that heat dissipation in the EOS R5 Mark II has been a big part of the engineering, and having two fast CFexpress Type B cards in there would obviously increase the heat that would have to be moved out of the camera.
There will likely never be a move to either the UHS-III or SD Express standards from camera or memory card manufacturers. The latest SD Express version 8.0 uses a dual lane PCIe 4.0 bus, which is the same as the CFexpress Type B 4.0 standard. However, the CompactFlash Association seems to be way more proactive in getting their standards to market than the always confusing SD Association.
The Canon EOS R1 will be going with a dual CFexpress Type B configuration. Which most EOS R3 shooters will likely welcome.

Yet another disappointment from Canon, while others seem to have little to none heat dissipation problems.
Only the Nikon Z9 has dual CFe Type B cards, The Z8 is CFe Type B & SD. Sony uses Type A which is a single lane standard. Type B is dual lane, hence the higher speeds and with that, more heat.
On my R3, I write raw files to both cards and usually use the SD card to pull the images off. Sure, the transfer speed is slower… But the overall process is faster since I can just stick the card in the slot on the side side of my MB Pro laptop or Stone Pro dock rather than having to dig out, connect, disconnect, and put away a dedicated card reader.
I wish computer cases came with SD card readers beside the USB ports. Multiple card readers are a pain.
I was very happy when Apple brought back the sd card slot in the mbp! Sd card for off load from camera is the simplest option for me. Not great for clearing buffer but switching to craw improves it

If Canon doesn't come clean and give us a pink R5, I'm going to switch to Sony.
I'd like to apologise to the EOS-1D X Mark III for my oversight.
I have only heard 4.0 from people in regards to the R52, however I haven't seen an actual official specifications sheet, so I can't be 100% sure.
I have a couple of Delkin 4.0 cards coming to get ready for the R1, which will be 4.0.
