Usually, it can be hard to visualize the contrast in sensor dimensions only by looking through technical specs. The pic below may give you a clearer sense of the sensor dimensions in the G100 and DP1x.

As you can tell, both the cameras have different megapixels and different sensor dimensions. The G100 using its smaller sensor is going to make shooting shallower depth of field harder and the Panasonic G100 will render extra detail because of its extra 15MP. Greater resolution will let you crop pics a bit more aggressively. The newer G100 provides an advantage when it comes to sensor tech.
