Typically, it is tough to see the difference between sensor sizing purely by looking at technical specs. The photograph here will help provide you a more clear sense of the sensor measurements in the K-S2 and K20D.

As you can tell, both the cameras provide the same sensor dimensions albeit not the same MP. You can expect the Pentax K-S2 to give you extra detail because of its extra 5MP. Higher resolution can also help you crop photographs more aggressively. The more modern K-S2 is going to have a benefit in sensor tech.
