Quite often, it is tough to imagine the difference in sensor measurements purely by seeing specs. The visual here will offer you a more clear sense of the sensor sizes in the WG-3 GPS and DP2s.

As you can plainly see, both of those cameras have got different megapixels and different sensor measurements. The WG-3 GPS featuring a smaller sensor is going to make achieving bokeh more difficult and the Pentax WG-3 GPS will show extra detail as a result of its extra 11 Megapixels. Greater resolution can also enable you to crop photos much more aggressively. The more recent WG-3 GPS should have an edge in sensor tech.
