Usually, it is very hard to visualise the difference in sensor dimensions only by going through specs. The pic here will help give you a better sense of the sensor dimensions in the E-PL3 and K-5 II.

All in all, both the cameras posses different resolutions and different sensor dimensions. The E-PL3 having a smaller sensor will make shooting shallower depth of field harder and the Pentax K-5 II will provide greater detail having an extra 4 Megapixels. Greater resolution will also enable you to crop pics somewhat more aggressively. The more aged E-PL3 will be disadvantaged with regard to sensor innovation.
