Often, it is difficult to visualise the contrast in sensor dimensions only by researching a spec sheet. The image below may provide you a more clear sense of the sensor sizing in the G3 and E70.

As you can see, the two cameras have got different megapixel count and different sensor dimensions. The G3 using its larger sensor will make achieving shallow DOF simpler and the Panasonic G3 will render extra detail with its extra 6 Megapixels. Greater resolution will also allow you to crop pics much more aggressively. The newer G3 is going to have an edge in sensor tech.
