The mirrorless I like is Olympus MFT because at least it has some advantages.  It produces very sharp photos and has a very deep depth of field.  It doesn't perform tremendously in low light but the 2x crop factor makes for some decent telephoto capability.  The sensor size is 16MP, and I'm not sure if it will get any bigger.

 

My point is, at least it can some things better than a DSLR.  It makes a great travel compact travel camera.  I sort of empathize with Canikon.  If I were to jump in (I don't have a mirrorless) It would have to be smaller and useful.  I don't think being exactly like a DSLR without a mirror is that compelling.  I'd be more tempted to add an electronic viewer to a DSLR and expand it's live view capability, which has sort of already been done. 

 

Note:  I don't own any mirrorless cameras so if don't talk out of experience.  But my premise is I would rather have a smaller format and smaller package if I was going to get a new camera system.  Having MFT, and Canon APS-C and Canon FF would be the best of three worlds.  But if the rest of the world wants to buy mirrors cameras, I'm sure they must have something going for them.

MFT does NOT have  a more deep DOF than FF and APS-C. You have the possibility to have a more shallow DOF with FF, but when closing down to the same aperture (equivalent f-stop), you get the same "deep" DOF on all formats.

 

MFT does have a size advantage of you go for smaller aperture lenses, and it does have a tele advantage.
