More often than not, its tough to visualize the gap in sensor dimensions merely by checking out technical specs. The pic below may give you a stronger sense of the sensor dimensions in the WG-4 and DP2 Merrill.

As you can tell, both the cameras provide different megapixels and different sensor dimensions. The WG-4 due to its smaller sensor is going to make achieving shallower DOF trickier and the Ricoh WG-4 will provide greater detail utilizing its extra 1 Megapixels. Greater resolution will also let you crop images more aggressively. The more modern WG-4 should have an advantage in sensor innovation.
