Oftentimes, it is tough to visualise the gap between sensor sizes purely by checking technical specs. The image below will offer you a more clear sense of the sensor sizing in the GH2 and ZR3.

As you can tell, both the cameras have got different resolutions and different sensor sizes. The GH2 because of its larger sensor will make getting shallower DOF easier and the Panasonic GH2 will give extra detail due to its extra 2 Megapixels. Greater resolution can also let you crop photos much more aggressively. The fresher GH2 is going to have a benefit with regard to sensor innovation.
