You are correct, and with diffraction I think that 24-30mp is approaching the limits of what aps-c can resolve. I know the theoretical ceiling is much higher, but realistically we are reaching the limits of current lenses. Look at the D800 for instance. So 18% more resolution. I welcome that. Nearly 20% larger is still a sizable increase IMO.
