Quite often, it is very hard to envision the gap between sensor measurements merely by reviewing specs. The graphic underneath may give you a clearer sense of the sensor dimensions in the DP1s and A300.

All in all, each of these cameras enjoy the same exact sensor sizing but not the same MP. You should expect to see the Sony A300 to deliver greater detail as a result of its extra 5 Megapixels. Greater resolution can also make it easier to crop images far more aggressively. The more modern DP1s is going to have a benefit in sensor tech.
