I'd like to wait and see. Not because of its recent EOS R release, but more specifically how they plan to slot in upcoming RF lenses and its impact on EF lenses. Selfishly, I had hoped that a native EF mount EOS R would have been ideal for my own needs. I would have continued to leverage my investment in EF lenses on my BM/DSMC2 bodies, while eventually transitioning back to Canon from Sony for my hybrid bodies over the next 2 years or so instead of maintaining two lens systems. Had the EOS R been more competent in its video performance, I would have even considered adapters to start, but as it stands, there is some real functionality that I use all the time that is entirely missing compounded with the uncertainty of Canon's lens ecosystem.
For now, I'll wait for the rumored EOS R pro-body in the next 6+ months at which point I might be able to glean some additional clarity on how all of this plays out. Canon really made a statement with its starting group of lenses, but it seems misplaced, at least currently with what they had to show with their first mirrorless release. Now that I'm also shooting Sony, I'm sure the A7Siii will also be a compelling upgrade for my needs as well in the near future.
On a side note, in terms of Canon's EOS Cinema lineup, will future C200II, C300 cinema bodies have the option of supporting RF? When I was shooting a C200, the 24-105II was excellent w/ DPAF, but some lenses were clunky. I would assume all RF lenses would be consistent, fully supporting DPAF with quick and smooth AF and aperture adjustments. More questions than answers at this point...
