Martin,
I'm confused by your question.
You seem to be inquiring about Image Quality (IQ) but don't want to discuss the noise differences?
Noise is probably the biggest IQ lever that there is!
Puzzled,

No, I'm not ignoring it. I'm saying that noise performance is evident on sensors with larger photosites. What I'm trying to look for is, if there is any other advantage to have a file that came out of a bigger sensor, but not particularly more megapixels, instead of a higher MP file from a cropped one.
My point is trying to understand if an image from an old camera with the same amount of MP but with "old time" noise and IQ performance would present a significant advantage over a new camera, with a cropped sensor, the same amount of MP but with new and improved noise response, surpassing the old camera, or at least getting closer to it.
I mean, the old 1D was an 11MP camera, with high ISO up to 1250. Now, the Rebel T3, for example, is a 12.2MP camera, roughly the same size, but with high ISO up to 6400. Is logical to assume that the T3 have much more improved electronics, photosite lenses, sensor design, S/N ratio, dynamic range and D/A converters, and thus will render cleaner images at 1250, or at least as good as the 1D.
Does the 1D images present any significant advantage over the T3 images?
