m4/3 for photos is stupid, ultimately. No optical viewfinder? No thank you... Mirrorless has it's place in small travel camera kits, and yeah things like the GH3 shoot solid video, but the thing is, their sensors END at m4/3. Canon, Nikon, hell even Pentax and Sony have far more sensor options that do just as well, and usually better than most m4/3...
and what with FF becoming a far more viable option to folks with 5dm2's and 5dc's selling for less than a 7D was brand new? and the new 6D and 600D coming out and telling folks that FF is becoming more affordable?
Making claims about EF lenses being non-native is silly - because eventually all those crop sensor guys are going to be throwing their awesome EF glass on a fullframe entry level DSLR... leaving m4/3s far far behind.
