I agree. One other angle to consider I think is how all current systems use hard cases for their games, so I imagine there will be less fluctuation of value based on the package's condition. People are probably less likely to throw away those hard cases, as opposed to the older cardboard boxes and loose manuals. Find a rare NES/SNES game with the box in good shape, and it can fetch high prices. Somehow I can't see that happening with DS games in all honesty.
