Typically, it is very difficult to visualize the difference in sensor dimensions purely by going through specs. The pic here might offer you a more clear sense of the sensor measurements in the E-M1 and E-P3.

As you can plainly see, both of these cameras come with the identical sensor size albeit different resolution. You should count on the Olympus E-M1 to provide more detail utilizing its extra 4MP. Higher resolution can also let you crop pictures a good deal more aggressively. The more recent E-M1 should have an advantage when it comes to sensor tech.
