Clearly, each of the cameras posses different resolutions and different sensor dimensions. The E-M10 using its smaller sensor is going to make achieving bokeh harder and the Olympus E-M10 will provide extra detail having an extra 1MP. Higher resolution will also let you crop photographs somewhat more aggressively. The younger E-M10 should have a benefit in sensor innovation.
