In many cases, its tough to visualise the difference in sensor measurements simply by viewing technical specs. The graphic underneath may offer you a clearer sense of the sensor measurements in the WG-4 and DP3 Merrill.

As you have seen, the two cameras provide different resolutions and different sensor measurements. The WG-4 with its smaller sensor will make shooting shallow DOF more difficult and the Ricoh WG-4 will result in more detail because of its extra 1MP. Higher resolution will also allow you to crop photographs more aggressively. The more modern WG-4 is going to have an edge in sensor tech.
