This is what I found from Nintendo's site... unfortunately I can't find any fiscal reports older than 2003, but this does at least give you a proper source for the sales.

If you scroll to page 48-52 the info you want about LTD sales is there (before you edit Wiki let me check the later reports to make sure they didn't ship more Gameboys after 2003)
