Have you ever tried filling the frame on a 2x3 format image. You can not crop to 4x5 format. You will wind up with a 10x6 image. Now the only solution is to shoot so loose that you have plenty of room to crop. But, that wastes pixels. Maybe that doesn't really matter. I'm sure for commercial photographers, it would matter.
This is why Olympus and Panasonic went 4/3rds. It is closer to the majority of the standard print sizes than 2X3 format. That means less cropping of pixels of the image and more "fill the frame" shooting with less worry of cut off. It is very rare for me to think about "shrinking" the image when I am shooting to make sure that I have the image. As long as everything is in my 4/3rds viewfinder, I shoot. Never have had to worry about whether I got the image such that it could be printed in any standard print sizes with the most pixels.
