Typically, it is very difficult to imagine the contrast in sensor measurements merely by looking through specifications. The graphic below should provide you a more clear sense of the sensor measurements in the GH3 and WG-1 GPS.

Plainly, the two cameras feature different megapixels and different sensor measurements. The GH3 with its larger sensor is going to make shooting shallow DOF simpler and the Panasonic GH3 will result in more detail because of its extra 2MP. Greater resolution will also enable you to crop photos way more aggressively. The more recent GH3 should have a benefit when it comes to sensor innovation.
