Sometimes, it is difficult to see the difference in sensor sizing purely by looking through technical specs. The visual below might give you a more clear sense of the sensor sizes in the G1 and G3.

As you have seen, each of these cameras have the same sensor dimensions but not the same MP. You can anticipate the Panasonic G3 to render more detail using its extra 4 Megapixels. Greater resolution will also make it easier to crop images a bit more aggressively. The older G1 will be behind with regard to sensor technology.
