Sometimes, its hard to picture the contrast between sensor sizing only by going over technical specs. The photograph here will help provide you a far better sense of the sensor sizes in the TG-3 and K100D S.

As you have seen, the 2 cameras provide different megapixels and different sensor sizing. The TG-3 using its tinier sensor is going to make achieving shallower depth of field harder and the Olympus TG-3 will deliver greater detail having an extra 10MP. Greater resolution can also allow you to crop pics more aggressively. The newer TG-3 should have an advantage in sensor innovation.
