Quite often, it is difficult to envision the difference between sensor sizing just by reviewing technical specs. The photograph here may give you a greater sense of the sensor dimensions in the X90 and DP2.

As you have seen, the two cameras have different resolutions and different sensor sizing. The X90 featuring a tinier sensor will make achieving shallow DOF more difficult and the Pentax X90 will deliver more detail having its extra 7MP. Greater resolution can also allow you to crop pics a bit more aggressively. The younger X90 is going to have a benefit with regard to sensor tech.
