Normally, it can be tough to picture the contrast between sensor dimensions merely by reviewing a spec sheet. The image below will help give you a far better sense of the sensor dimensions in the VR-320 and 645D.

As you can see, each of these cameras have different resolutions and different sensor dimensions. The VR-320 having a tinier sensor is going to make achieving shallower depth of field more difficult and the Pentax 645D will offer you more detail because of its extra 26MP. Higher resolution will let you crop pictures a bit more aggressively. The newer VR-320 should have an advantage with regard to sensor innovation.
