Actually, I myself don't care how good the E-410 is. I'd much rather have a E-510 than a E-410
I don't think you will ever see a sensor that is as great as it can be. I'd say the increase in resolution of the sensor will be somewhat of a negative towards image quality. Who knows about the "maker" of the sensor. Might be a negative, might be a positive. Might be a wash.
