I previously mentioned that we'd be getting new adapters in 2020 for the RF mount, but I wasn't sure which adapters were coming next.
I have been told the following adapters will be coming this year.
- PL to RF with Cooke/i
- EF-Cinema Lock to RF
- Speedbooster (Perhaps for 4K recording on the EOS R)
There are usually announcements from Canon and others at the end of August or early September, so I suspect we'll see these announced some time around then, along with new RF lenses.
I think the speedbooster is for super-35 sensors, and maybe also for cropped modes.
I'm thinking the speed booster is for the future APS-C R series. That would be awesome!
If this rumor is true, and that a cinema to RF adapter is being offered, does that mean:
I don't know if such adaptors were expected or a very big piece of news. Which is it, and why?

I think you're overthinking it. An RF Cinema camera is coming. Cinema people will want to use both PL and EF mount lenses on it (hence those adapters). Canon will likely release cine RF lenses eventually, but those are quite some time away.
Will AF still be possible with the canon speedbooster
An FF to APS-C speedbooster would make a 800mm/11 FF image circle lens a roughly 500mm/7 crop image circle lens for all intents and purposes. That is, you’d get the same exposure, noise, diffraction, FoV and DoF on crop as on unboosted FF. I doubt Canon would release a booster that’s not compatible with AF.
The RF lenses have a much newer, faster 12-pin communication system, e.g. they are not backwards compatible with anything, only RF-mount cameras.
