Eventually the rationale of having native glass for my camera bodies, not using adapters, etc, will win me over. But I am still happy with my EF glass waiting for something like an RF 50-135 f/2; 200-500 f/4, 14-20 f/2, 100 f/1.4 or smaller and lighter weight compared to what I have.
Barring the 50-135 f/2 type of lens, I expect the 70-200 f/2.8 to end up in my bag. If it has better bokeh than my 70-200 f/2.8 II IS, great. But, it'll primarily be about size/weight/native glass.
