That said, some CFExpress cards can fit in an SD slot so Apple could choose to support both (type A) but AFAIK only Sony uses this format. Nikon and Canon use type B, which is larger.
Type B uses the same slot as XQD, which has been around since 2012. I doubt we will see pro grade card slots built into consumer oriented computers any time soon anyway. SD is good enough, since it’s more common. Many pro cameras have SD and XQD/CFexpress type B slots anyway. I’m more than happy to use an external for my XQD and CFexpess (type B) cards, since you need to upgrade your reader every few years to take advantage of the speed of newer cards.
