Often, it is tough to visualise the contrast between sensor dimensions purely by going over a spec sheet. The image underneath might give you a greater sense of the sensor sizes in the TG-3 and DP2 Merrill.

As you can see, both the cameras posses different megapixels and different sensor dimensions. The TG-3 having a tinier sensor will make getting shallower depth of field tougher and the Olympus TG-3 will deliver extra detail having an extra 1 Megapixels. Higher resolution can also enable you to crop shots somewhat more aggressively. The more modern TG-3 will have a benefit in sensor innovation.
