Sorry, this camera cannot exist as pictured so it is probably fake.
The mount appears to be EF for the EOS system, and the camera itself is marked 'EOS'. But then the register distance from the mount ring to the sensor is nowhere near deep enough, so there is not a single EF or EF-S lens that will be able to focus on this camera. I know this lens says 'EF-M' but I kind of doubt Canon would launch a new lens line that was so easily confused with the existing EOS system. I bet they would work to make it more clearly different.
So to me this is almost certainly bogus. Any camera with the dimensions of this one will not be 'EOS' and will not have an EF lens mount. It would have to be a totally new lens system. EF and EF-S lenses would only mount with an adapter that provides the necessary depth.
EOS stands for "Electro-Optical System". It doesn't stand for "44mm flange distance". So there is no reason why this couldn't be an EOS camera.
They have also already shown a willingness to introduce a new EF system that is not backwards compatible with the existing one, EF-S. So for them to make another one, EF-M, is not really surprising at all.
Besides, a simple adapter would let both EF, and EF-S lenses work on this system. The real concerns will be people buying EF-M lenses and having them not work on EF-S and EF systems. But that is the case already with EF-S lenses on EF, so again, willingness to do so already a given.
The other concern is the AF system, as contrast detect systems and phase detect are very different, and lenses optimized for phase detect may not AF too well on a contrast only system. (An issue the 4/3rds m4/3rds systems ran into with a few lenses). But again, a minor concern when introducing a new system like this.
