Don't worry, I don't like that word too! I have re-added it there, because I expected someone to jump on that. Hey, it has worked
Your point might be interesting, but where we differ is, that I actually think, that there are some things, which could/should be common as a "standard". For me it is IBIS, AF-ON, tilty-flippy from now on, for all R based bodies. Don't get me wrong - 5D line, both in terms of DSLR and MILC, does belong in the professional area.
We will see, who of us is right. R5 might be developed by completly different team than 1DX III. Maybe R5 team did not have enough of time to incorporate it into R5. We will see, if in 1-2 year timeframe, new AF-ON appears on even cheaper bodies. And if so, then it sucks. If they keep it to just the 1D line, well then ....
