8Mpixel does pose an advantage over 6Mpixel, presuming all else is equal. I disagree with your comment "Just because one does not immediately perceive it [higher resolution] in a given shot, or at particular print size, does not mean it is not there... ". The improvement is simply small and is not noticeable until you get to very large sized print output. With a photograph, unless you can see the resolution in the image at some print size, it isn't there.
The cropping advantage is there but it's modest. For instance, the Canon 20D produces 3504 x 2336 image resolution vs the *ist DS 3008x2008. That's a 496 x 328 pixel difference, not nothing but only enough for about a 5 degree rotation at best without cropping the 6Mpixel image. Given the choice of an updated, improved *ist D or DS with 8Mpixel as the *only* improvement, I'd pass. It's not *enough* of an improvement to warrant buying a new body, for me at least.
