Nintendo president Saturo Iwata has mentioned that older Nintendo games may get a new look when you download them on the upcoming Revolution online service.
"We are doing several experiments, including working with the original Super Mario Bros., with the new technology. The game itself and the gameplay shall be identical, but the look will be different; it's possible that with Revolution, we may be able to see the old games with new looks."
The most obvious application is that NES games could get the "Super Mario All-Stars" trearment - nicer sprites and backgrounds added to the same game engine. But what about the 3D games of the Nintendo 64 promised for download? Apparently some work has gone in to making the N64 games "look sharper" when played on Revolution. Does this mean higher framerates and resolution?
Hopefully 'classic' modes will also be available on games that do get makeovers. But increasing performance on N64 games is certainly welcome - as anyone who has the Gamecube Zelda bonus disk can tell you.
