Sometimes, it is very hard to visualise the difference in sensor sizing merely by viewing technical specs. The photograph here will give you a much better sense of the sensor measurements in the EX-G1 and DP2 Quattro.

As you have seen, both of the cameras have got different megapixels and different sensor sizing. The EX-G1 because of its smaller sensor will make getting shallower DOF harder and the Sigma DP2 Quattro will provide you with more detail due to its extra 8MP. Greater resolution can also let you crop images much more aggressively. The older EX-G1 will be disadvantaged when it comes to sensor tech.
