I don't see Canon announcing an R1 without a couple of RF big whites. The lenses adapt flawlessly, but they will want to make a splash of a fully baked RF Pro solution.I have predicted just this for some time. An engineering intern could work on the rear housing needed to create RF versions of both the 400 iii and 600 iii models. Presumably the 300 f2.8 ii is to be updated with the iii series lightening, and will also be released as an RF. (Canon's data will tell them whether to bother including an EF variant or demountable adapter). RF variants (without optical redesign) of the 200-400 and others might also be done, but lenses that are older than 10 years are more likely to await a real update.
This, perhaps in addition to the rumored 250/250/500 F2/2.8/4 that will do it all for me. (I note that this makes me weigh whether the 250 f2 would be a DO to differentiate.
The real question is whether any of Canon's new big whites will ever be made in EF or if the 400 and 600 were the last.
The "dog that didn't bark" is the lack of Canon releasing any RF versions of existing EF lenses. This tells me they plan plenty of new designs for RF, or a flurry of them for the R1 announcement.
The new lenses might well be announced alongside the R1, imaged surrounded by a forest of new RF big white lenses making the R1 the definitive champ.
