Mirrorless opens up new optical formulae: More freedom in terms of lens design like e.g. lens elements near the sensor. You have to avoid confusion with the standard EF mount - so a new mount is mandatory IMO.

I am shure there will be a small selection of native EF-X-mount (or whatever it name will be) lenses of shorter focal lengths and an adaptor to adapt EF lenses.
Is Sony just too dumb to use that freedom in terms of lens design as they keep releasing E-mount G-Master lenses that have the rear element 40-50mm from the sensor with some empty lens barrel as a spacer? Or could it be that the 'freedom in terms of lens design like e.g. lens elements near the sensor' comes at the cost of a hit on image quality?
There's no need to 'avoid confusion with the standard EF mount' if future Canon FF MILC's just use the EF mount.
As for a new MILC mount, there's already an EF-M mount...quite simlar to the Sony E-mount. If there's some new mount for FF MILC, unless those lenses can natively mount on EOS M bodies (as EF lenses can mount on APS-C dSLRs), then that new mount is likely a non-starter from a commercial standpoint.
I think we're going to see a Canon FF MILC that either uses the EF mount (seamless compatibility for curent users, maintain lens lineup), or the EF-M mount (providing a direct upgrade path for EOS M users). A brand new mount that lacks native compatibility and thus alienates both current buyers and future APS-C MILC buyers is really unlikely.
