Generally, its tough to visualize the difference between sensor sizing purely by reading specs. The photograph here may offer you a greater sense of the sensor dimensions in the E-M1 and A37.
All in all, both the cameras have the same resolution but different sensor sizing. The E-M1 features the tinier sensor which should make getting shallower DOF trickier. The fresher E-M1 should have an advantage with regard to sensor tech.
