The E-M1 does look like a beautifully designed camera! I am pleased to see Olympus re-committing to the "serious" or semi-pro micro 4/3 concept, and I will be tempted to upgrade from the E-M5. For me personally, the most appealing new features are the slight increase in size with a bigger built-in hand grip, better ergonomics overall with more space for buttons, and more direct controls for easier adjustments without looking at the camera, better EVF, focus-peaking, and built-in WiFi with remote camera control from a mobile device. The improved autofocus is also nice but less important to me because I use a Nikon D7100 system for telephoto/autofocus bird photography. I don't think the new E-M1 sensor will show significant or noticeably better image quality over the E-M5.
