Quite often, it is very tough to picture the contrast in sensor sizing only by going through a spec sheet. The visual underneath will provide you a much better sense of the sensor measurements in the K-S1 and H20.

As you can see, both of those cameras enjoy different megapixel count and different sensor sizing. The K-S1 because of its larger sensor is going to make achieving shallower DOF simpler and the Pentax K-S1 will produce more detail as a result of its extra 10 Megapixels. Greater resolution will also make it easier to crop pics far more aggressively. The fresher K-S1 provides a benefit when it comes to sensor technology.
