Sometimes, it is very hard to visualise the difference in sensor dimensions just by viewing technical specs. The pic underneath will give you a more clear sense of the sensor sizes in the PX and DP3 Merrill.

As you have seen, the two cameras provide different megapixel count and different sensor dimensions. The PX due to its smaller sensor will make achieving shallow DOF trickier and the Ricoh PX will render more detail as a result of its extra 1 Megapixels. Greater resolution can also make it easier to crop photos more aggressively. The more aged PX will be disadvantaged with regard to sensor technology.
