The key to R5 specs is sensor read speed. In this aspect, canon has leapfrogged competition similar to how Apple did with iPhone back in 2006. This is why Canon was comfortable announcing the specs months before release without fearing competitive catchup.
Given that Sony makes sensors for pretty much all other major players, we can not expect a camera with competing specs, from any vendor, until Sony semiconductor can produce a sensor with similar read speed.
Sony A9/A9II still have faster read speeds than the R5. We don't know what the R5's read speed is but they still have a footnote that says you can expect banding in certain light sources in e-shutter. That alone tells me it isn't as fast as the A9 because the A9 has eliminated that issue.
There is no way the R5 is 1/160 like the A9/A9II.
Multiple people have commented on this. We (either you or I) are confusing read speed (which is sheer data transfer rate) vs scan speed (scan from top to bottom). A9 still has a faster scan, but Canon is reading 45MP x 20 in electronic shutter and moving it into buffer (with upto 180 Raw). I understand that this is not useful for Sports shooting if scan speed is slower, but as 1Dx III shows, it is still considerably faster than A7 and Nikon Z and will work well for action where subject is not crossing the frame horizontally. For example a runner coming towards the camera, or birds in flight where camera is also usually panning with the subject.
The real benefit, however, is in the video specs which are through the roof. 8K/30 and 4K/120 for a full frame in Raw or 10-bit ! Sony is still struggling with 4k/30 being limited to 8-bit. A7S III might change that (we will know soon), but it will be a low MP camera.
