I expect that Zelda, Metroid and Mario will remain on the charts for a very long time and will likely see a sales boost when they (eventually) become a 'Platnium Hit' and sell for $20/$30 ...
Mario and Sonic at the Olympics seemed to be released at a very odd time; had they taken the additional 6 months to polish the game and started selling it right before the olympics it would have seen much better sales. It still could see quite long legs because the olympics are bound to cause increased interest in this title.
