Usually, it is difficult to visualise the difference in sensor sizes merely by viewing a spec sheet. The pic here will help provide you a more clear sense of the sensor measurements in the E-P2 and K-3.

Clearly, both the cameras feature different megapixels and different sensor sizes. The E-P2 with its smaller sensor will make getting shallower DOF trickier and the Pentax K-3 will render more detail because of its extra 12 Megapixels. Higher resolution will help you crop shots way more aggressively. The more aged E-P2 will be behind in sensor tech.
