As you have seen, each of these cameras provide different megapixel count and different sensor sizes. The E-PM2 having a tinier sensor is going to make getting shallower depth of field tougher and the Olympus E-PM2 will deliver greater detail with its extra 2 Megapixels. Greater resolution can also enable you to crop images more aggressively. The newer E-PM2 should have an advantage with regard to sensor tech.
