Well, I'll be picking up my A7r later today on the way home from the Upscale Mega Mall (where my friend Bruce & I are drinking coffee, chatting, people watching and typing away on our respective gizmos). So we'll see how it stacks up against the E-M1 in our opinion. When I told Bruce what I had in mind for the Sony (16:9 aspect ratio, downsampling, no printing, Y/C Zeiss lenses) he looked at me like one of my eyes had fallen out. But after many emphatic repetitions of "4K is the Future, dude!" he seems less perturbed.
