Very interested to see if Canon will introduce a new mount. I like the Canon approach of not making a big fuss.

Rumors are there will be a Canon FF mirrorless announcement next week

To be expected Nikon and Canon do a dance, a symbiotic one.
That said, Canon does make a fuss, when they have something to fuss about. Juts that for a long while, their bodies have been not much to shout about.

All companies make a big deal when they can; that's called marketing.
If Canon does make an announcement they will make a big deal; just wait and see.
Also when Canon does enter the FF mirrorless market, then any hope that Sony had of using mirrorless to capture a larger share of the market goes away.
So am I. They already have a large 54mm throat diameter. I wonder whether they will stick to the EF mount or use the EOS EF-M mount?
It will probably use the EF-M mount I guess. It has an 18 mm flange focal distance (compared to 44 mm for EF and EF-S) and a 47 mm throat diameter (compared to 54 mm for EF and EF-S). It is designed for use with an APS-C-sized image sensor, but I guess it could accommodate FF as it is already 1mm larger than the Sony FE mount which was also designed for APS-C.
If Canon use the EF-M mount that will leave Nikon as the only company to have a mirrorless FF mount specifically designed for FF optics.

Agreed, Sony's huge mirrorless venture just got tougher with Nikon Z and will again with Canon's.
But, thank you to Sony for stirring the market up and making it more competitive.
We can thank them for that.

Hence, why Canon will not use the older mounts.
Previously Canon has shown willingness to cut ties and move forward.
They will again.
The large diameter and short flange distance enables better optics, which is why Nikon has done it.
No way that Canon will allow Nikon to have such a huge advantage.

Apparently, Nikon use their DSLR live view AF system which is nothing to write home about. Canon dual AF could be a big advantage. I hope Nikon improve AF before launch, otherwise they'll have the weakest AF in the full frame mirrorless world which is a shame since they have the best in their DSLR system!
Wow what a nonsensical comment. !!
So you are basically saying that Sony and Canon came with a next generation mount E and M for the next 20 years haphazardly ?! It never occurred to them that they could use these new mounts for FF sensors?! LOL so FF was like an after thought ?!
Jumpin jeeezers Jim Jam! why of why Sony and Canon designed a throat that is much larger than APS-C if it was made for it exclusively !!

True to Canon, they will introduce a camera with the lowest featureset possible, in a consumer body, at a competitive price. I expect zero innovation, just a mix of M50, 80D and 6D components. Pack a FF sensor in it and hope your users stop migrating to Sony. It probably will work.

Yeah, Canon is no-nonsense. They like to announce, ship a ton, then haul their money to the bank.

Should be interesting. All Canon needs to do is offer dual card slots, and it's a win for them, IMO. Not sure how many pros really want to go ML, but the ones who do will likely choose the pro camera, which the Z cameras are not.
I think you need some engineering lessons:
A throat diameter of 46-47mm is suboptimal for freedom of design with FF lenses. It is true to say that Nikon Optical engineers decided on a FF mirrorless mount unrestricted by APS-C origins.
Consequently Nikon has a problem in reverse. If they want an APS-C sensor in the Z mount it will be too large.
I think you need some engineering lessons.
The Z-mount is not "too large" for APS-C sensors. APS-C in a Z-mount will work just fine, with plenty of room for IBIS, and large barrel diameter to prevent vignetting; and Nikon can actually make smaller DX "Z" mirrorless cameras than DX "F" DSLRs.
Several mounts have high image-circle to mount diameters. For example, Nikon's own Nikon-1 mount had a 40mm diameter, while the image-circle/sensor diameter was less than 16mm. I don't remember people complaining about it being too big for its sensor size.
55mm is not a particularly large size. Most mobile phones today are roughly 70mm wide. In theory, Nikon could make a Z-mount camera of any sensor size below FF, that is smaller (though thicker) than your mobile phone.
I don't really give a damn about APS-C. That was just a passing comment. I still hold by my original assertion that Nikon will be the only company with a mount specifically and optimally designed for FF mirrorless, if Canon adopt the EF-M mount for FF.

I keep hearing how this bigger mount will allow such great lenses, but not sure that's really a problem now. There are plenty of F-mount, FX lenses that are spectacular already. So what? These new Z lenses will be a little sharper in the corners, and have less vignetting? The price to pays is, there will hardly be any native Z lenses for many years to come.
Canon already has a great selection of excellent glass. If they keep the same mount, they will have ALL those lenses available right away. No cumbersome adapter required. Guess we'll see what they decide to do. If they go ML with the same mount, and have 2 card slots, I think they will decimate Nikon.
If you don't care about APS-C, then you shouldn't have responded to a comment about APS-C.
I do care about crop formats because they are a cost effective way to drastically increase reach & speed. If I want to take a detailed picture of the moon, for example, I can either use a 500mm lens on a Nikon D850 and crop to fill the frame; or I can use that same 500mm lens on a Nikon 1 J5, which has 3x the resolution of the D850. If the silicon used for the J5 was cut to a full-frame sensor, it would be 150MP.
Sensor cropping with higher pixel density is the modern response to teleconverters.
The OP raised a question about what mount Canon might use for its new FF mirrorless (if in fact they do anyhting
. I'm suggesting they might use the EF-M mount which they introduced for APS-C mirrorless. If they do that then its my assertion that Nikon will then be the only camera maker with a mount specifically designed for FF mirrorless. I'm not really saying anything else.So what Sony and Canon have done, both of them, is design a mount that suits APS-C, and then shoehorn a FF sensor in later which just fits. I'm sure they had plans along those lines in the early design stages, but nonetheless that's the order they did it. Nikon have come at the new mount design in the reverse direction, favouring a design that specifically suited FF.
It's also possible that Canon could use the DSLR EF mount dimensions (54mm diameter) and shorten the flange distance to 16mm like Nikon. Unlikely but. Let's wait and see
