I just wish they announce both at relatively similar times so we could choose. I think many of use would like to have the opportunity to weight their decision between both.
I'll buy the R1 if it has significant advantages to me over the R5 II : significant more MP (ex 60 vs 45), significant larger/better EVF (please make those huge), or faster/easier way to select people when several are on screen (R3 eye focus don't work with my correction). I would not care much about the rest (although I do enjoy the many 1D benefits), I'd rather go R5 II otherwise (I went from 1Dx to 5D4 as I much needed the MPs) which frankly is my likely choice.
I am sure both cameras will perform well. It is not all about the specs, even if I expect them to play catch up, since they are quite late - the Z9 is more than 2 years old now. But let's remember they did not cheap out on the R5 and it was and still is a great, well rounded camera, that did not feel crippled in any way like some of their past offers (I went 1D3 instead of the 5D2 because I dearly needed precise and fast AF points spread out from the center).
My own concern is time of availability for whatever camera I pick. What I shoot simply disappeared during covid, so I could not shoot during 2020, 2021, and most of 2022, so I choose to skip one generation (the R5) thinking the replacement would come in 2023 due to competition pressure and there were no RF lens I really wanted save for the 85.
If R5 II only comes out end of summer, it means I can start using it in the autumn, then in hindsight the best decision would have been to get the R5 back in mid 2022.
Anyway, wait and see.
