CFexpress Type B has become widely used, and the transfer speed is steadily increasing. Finally, Nextorage (formerly Sony's flash memory division) announced a Type B product with a write speed of about 1900MB/sec. In contrast, CFexpress Type A is only used by Sony in the α7 series and α9 series, and no other manufacturers have entered the market. It's still a wait-and-see approach, but as video progresses to 4K and 8K and recording speeds improve, it can be said that SDUHS-II is now outdated. However, many users still use SD UHS-II. This is mainly for cost reasons. However, SDUHS-II will eventually become a legacy standard, so it is desirable to converge to the next generation recording media soon. CFexpress Type B is ideal because it has a fast transfer speed and there are products with large capacity, but the drawback is its size, which means that the camera body will become large to make it a double slot. Type A is easy to make into a double slot because the media is small, but the transfer speed is currently only 700-800MB/sec. And the fact that Sony is the only manufacturer to adopt it seems to be preventing its widespread use. What will happen to the next generation of recording media?

Addendum: Canon announced that its cameras were the top press camera users at the Rugby World Cup in New Zealand, averaging about 75%. Cameras used were EOS R3, EOS-1D X MarkIII, and EOS R5.
