Canon R3

[Fast Glass]

And the other thing is, despite a few little things and watch all the reviews I can. It seems like the R3 is just better.

The unlimited buffer of the 1Dx III is nice along with 20fps mechanical, but really. Is it worth trading better noise performance, better resolution, better dynamic range, IBIS, more than likely better AF especially with native glass, incredibly sharp and fast focusing RF glass, being still able to shoot all your old EF glass, 30 fps and more. Just so you can be trigger happy?

I suspect that for most people that it's not worth trading basically everything good about a camera just for that. Even for the most hard core shooters.

And it begs the question, will there be a price drop for it? Because it doesn't offer enough advantages worth even considering especially when it is $500 more expensive.

Maybe if it was $500 less, but even then. Anyone with that kind of budget would they really want the 1Dx III for $500 less? Probably not.
