That's what I originally thought, but it's not true for wide-angle lenses. Particularly with sensors being smaller than a traditional 35mm frame, it's difficult if you want to shoot really wide images. You can spend the extra bucks on an EOS 1Ds or one of the Kodak bodies to get a full-frame sensor, but the Nikon DX lenses seem very attractive, particularly for their weight savings. You get many of the benefits that are normally claimed for the new 4/3 system, but you have backward compatibility to decades of used lenses.


I haven't verified this, but my wife claims there's a lens you can only buy from Canon if you buy it with a Digital Rebel which is a 180 degree wide angle lens. I don't know the details, when she's next awake I can ask if you like.
