"We are doing several experiments, including working with the original Super Mario Bros., with the new technology," said Iwata. "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."
One question remains, however. Will only some games look different or will the Revolution hardware itself give them a different look automatically? I still believe that a technology like AR is a possibility.
