Generally, it is very tough to visualise the difference in sensor sizes only by seeing technical specs. The pic below will give you a far better sense of the sensor sizing in the K-1 and WG-1 GPS.

As you can tell, the two cameras have got different megapixel count and different sensor sizes. The K-1 with its larger sensor will make achieving shallow DOF easier and the Pentax K-1 will provide extra detail using its extra 22 Megapixels. Greater resolution can also make it easier to crop photos much more aggressively. The younger K-1 is going to have a benefit with regard to sensor innovation.
