RF 70-200 may be able to use the TCs? is this not the best news we could hear this year so far (70-200 owners?)
All RF lenses to boot? Canon working some real magic this year.
maybe if you put on the EF to RF adaptor first?I am not seeing how that would be possible given the protrusions on the teleconverters and the position of the rear element on many current RF lenses.

Regarding the “cool” adapters coming, this has got to be 1.4x and 2x flip-switch TCs for EF big whites. Then all eventual RF big whites would have a removable rear segment to reveal an EF mount so they could be used on a DSLR (at the slower EF mount communication protocol) or accept the flip TCs that engage the extra RF connections.
RF Big Whites:
All intact — RF mount
Rear segment removed — becomes EF mount
Rear segment removed — accepts flip-TCs
This way there would additional functionally added to EF big whites, making those that use them want to switch to R bodies. And Canon could wait to make RF big whites until the next planned upgrade cycle for each lens since the urgency to deliver big white RFs would be removed.
Don’t forget, the 300 2.8 II, 500 f4 II and 200-400 f4 were not updated in the last EF round. I think these will be our first big whites for RF with weight reduction and slightly improved optics. Maybe, the 200-400 will be stretched to 200-500 f4 and they dont bother updating to a RF 500f4 IS.Regarding the “cool” adapters coming, this has got to be 1.4x and 2x flip-switch TCs for EF big whites.

More cool adapters? That’s... cool.
If the RF 70-200 f2.8 L IS can work with the 2x converter, then I hope it will result in a good IQ for 140-400 f5.6. If so, then it would take some pressure off of trying to decide which (current or future) long tele zoom to get. All in all, it's great news!
Removing a rear segment from an RF mount to reveal an EF mount, is not even possible.

Totally agree. I'm new to using longer lenses, not that the 70-200mm is classed as a long lens lol. also great for the 24-105 as an even more useful walk around lens, albeit reducing the F to f8.If the RF 70-200 f2.8 L IS can work with the 2x converter, then I hope it will result in a good IQ for 140-400 f5.6.

This has mostly been a limitation of DSLRs as their AF systems have so little light to work with (and I think they need larger cone anyway). Sony's A9 does fine(ish?) at f/13 for example.my only concern after reading some TC reviews is how it may affect AF as some have said the AF doesn't work as well. That would be a pain for the odd occasion I do wildlife but the benefits would still outweigh it.
