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

Why would owners of Canon FF DSLRs want the expense of buying a whole new set of lenses?

And it would give Sony an opportunity to say "as long as you need to buy new lenses, you should switch to us, because we have more native lenses".

.... and better sensors, and better AF, and better video, and robust third party E mount lens support, and very functional EF adapters from Sigma and Metabones.

And better (richer, more dynamic and more authentic) colors, better high ISOs especially IBIS gain several stops with lenses without 'IS' as TS-E lenses shown, cleaner and more details in long exposed photos where Canon sensors falling apart - low DR, low S/N ratio and color shift if you push shadows aggressively as have seen. Canon not only needs mirrorless (if DSLR is so good why now both Nikon and Canon wants to jump into FF mirrorless bandwagon) but needs much better sensors.

Canon fanboys want you to believe DPAF is the best. It's NOT. Not only it is no match in AF-C (otherwise why Canon owners still shoot sport and BIF in OVF via separate AF/AE sensor), but also dual pixel now shows more negative than positive impact, and just unpractically many times holding a DSLR as a cellphone camera, under bright sunlight? Because of dual pixel, despite Canon also has sensor-side ADC, its best DR in 5D IV still less than 5-year-old A7's sensor, no mention in A7r II/III sensor. And it becomes a bigger and bigger burden to move double amount of pixels around that impacts IQ and limit burst rate and buffer depth. That's why 5Ds/R don't have DPAF, and wait and see if 5DsR II also will not have DPAF as it'd need to move 100mp data around otherwise that is a huge burden. Canon needs to adopt on-sensor hybrid AF (DPAF+CDAF) as everybody else does, but needs lots of R&D. In history Canon never good in CDAF as we have seen in its compact and M-series and no experience in on-sensor PDAF, so it's a huge capture-up task.
