just wanted to add another angle:

since (i think) you mentioned shooting landscapes, you might experiment with shooting them in segments and then stitching them together in order to cheat the resolution problem. for example, you divide your scene into a grid of 9 segments (3x3) and photograph each on of those. then when combined, you get a much larger image at native resolution. it's what i do because i can't afford digital backs either! (still have my mamiya rz waiting though...)

Thank you, bocomo! Compuwar suggested the same! Though more cumbersome, stitching will overcome the shortcomings of 12MP (4000 pixels along long edge) enlarged to 13 x 19. This is a viable technique since I had been accustomed to using a tripod for my b/w landscapes done with film. However, it wouldn't work for those many "grab shots" that turned out to be great compositions.

Thank you, Sonor! Thom Hogan's article addresses just about everything that was mentioned in this thread. His chart comparing sensor MP size/print size/image quality puts it all in perspective. He makes a great argument against going MP crazy.
