To sum up, the 2 cameras have different megapixels and different sensor measurements. The DP2 Quattro because of its tinier sensor will make getting shallower DOF more difficult and the Sony A99 will resolve more detail due to its extra 4 Megapixels. Higher resolution can also enable you to crop pictures a bit more aggressively. The more recent DP2 Quattro will have an advantage when it comes to sensor technology.
