Will Canon's FF Mirrorless be EF or EF-M Mount?

I think it will be an EF mount. Canon has shown little interest in developing the EF-M mount in any serious way and they have a massive investment in the EF catalog. If anything I think they will offer a variation of the EF-M mount that will be like the EF mount is to the EF-S mount. Also, if they offer a serious FF MILC that is targeted at professionals then having an EF mount is critical to its success, IMO. Otherwise, they would have to launch 5-10 new, high quality lenses along with the body and I don't think Canon will take a risk like this.

Lastly, we have seen that when it comes to professional, bright lenses the size/weight advantage of any MILC vanishes which further pushes the mount toward EF. I think it would be smart if Canon allowed the FF MILC to use EF-S lenses in a crop mode for the sensor. This would let a user take advantage of the small, lightweight, STM EF-S lenses they are offering. Basically, it would give the new FF MILC the ability to go small and lightweight if the user wanted to.

You actually made me wonder about this. I have the M3/M5 and they both work flawlessly with the adapter Canon provides so even if it was an EF-M Mount body, I know the adaptor wouldn't have an issue.

Now onto my crazy theory. With the current mounts, it's undeniable that EF gets more love than EF-S lenses. Now considering we have hardly had any new EF-M lenses and minimal EF-S lenses, what if this is because Canon shifted their focus onto FF EF-M lenses to launch alongside the new body? The body would have no issues using the EF-M adapter so we could have some lenses made just for the new mirrorless body as well as all our existing lenses.

It is just a wild theory but could be feasible too.

I think about anything is open for speculation right now. If you are right then it still doesn't explain why they virtually ignored the EF-M mount for its first four years. Maybe they are turning the EF-M mount into the mirrorless version of the EF-S mount. That is the will both be slaves to the EF mount. Just like when a person moves to FF from ASP-C DSLRs they forgo use of their EF-S lenses the EOS M APS-C user might have to do the same with their EF-M lenses. This would explain the lack of EF-M lenses, in general, and higher end ones.

When it comes to why they ignore the EF-M Mount for its first 4 years, there could be multiple reasons. They may have wanted to see how popular it would be before they invest money into r&d for more lenses. Canon may have expected people to mostly use their EF/EF-S lenses adapted with these bodies and figured more lenses could wait.

I know I'm 90% sure I'll be getting the FF Mirrorless once released and I have no problem using an adapter since I do that already with my M5. Considering G Master lenses are the same size as their Canon L lens counterparts, the main advantage of having them as an EF-M Mount (assuming Canon dont find some way to reduce the lens size while providing the same IQ) the only advantage would be that small weight and size saving you would get from not using an adapter.

I think the pecking order of the probability of Canon FF MILC mount is EF first, a new MILC FF mount second and the EF-M mount third. Knowing Canon's history of product differentiation, I don't think they want their flagship FF MILC(s) slumming around with an EF-M mount. Plus, there might be confusion between APS-C and FF EF-M lenses if the current batch of EF-M lenses will not work with a FF sensor.

i think current APS-c M will stay very compact ...if that's the case because of the laws physics we will not be getting F1.4 lenses

i think the FF MILC will not be compact ....well the body's may go down in size a bit, but its still going to be able to handle a 400mm F2.8
