Normally, it is very hard to visualize the contrast in sensor sizing purely by researching technical specs. The graphic underneath will help give you a more clear sense of the sensor dimensions in the DP1 Merrill and A7R.

As you have seen, each of the cameras offer different megapixels and different sensor sizing. The DP1 Merrill due to its smaller sensor is going to make achieving shallow DOF more challenging and the Sony A7R will render extra detail utilizing its extra 21 Megapixels. Greater resolution will let you crop photos a little more aggressively. The older DP1 Merrill will be disadvantaged in sensor innovation.
