More often than not, its hard to see the contrast in sensor dimensions just by researching a spec sheet. The image here will provide you a much better sense of the sensor measurements in the E-P3 and T90.

As you can see, the two cameras feature the identical megapixels albeit not the same sensor dimensions. The E-P3 uses the bigger sensor which is going to make achieving shallower depth of field less difficult. The fresher E-P3 will have an advantage in sensor technology.
