As you have seen, the two cameras offer different resolutions and different sensor sizing. The E-P2 using its tinier sensor will make achieving shallower depth of field more challenging and the Sony A77 II will offer you extra detail because of its extra 12 Megapixels. Higher resolution will enable you to crop photographs a little more aggressively. The older E-P2 is going to be disadvantaged when it comes to sensor innovation.
