Quite often, it is tough to envision the contrast between sensor sizing just by going over a spec sheet. The visual below will give you a clearer sense of the sensor sizing in the XG-1 and SD1 Merrill.

As you can see, the two cameras posses different resolutions and different sensor sizing. The XG-1 using its tinier sensor will make getting shallow depth of field tougher and the Pentax XG-1 will offer you extra detail having an extra 1MP. Greater resolution will also make it easier to crop pics somewhat more aggressively. The newer XG-1 is going to have an edge in sensor innovation.
