Did you know that the GameCube was built with some specific 3d technology that was never put to use? The info comes straight from Iwata himself!
Iwata: To tell you the truth, GameCube is secretly designed to load graphical circuits which display graphics for right and left eyes respectively, for a future possibility of realizing 3D gaming experience. So actually we have had interest on this technology, but I have some doubt about everyone needing glasses to play.
Looks like Nintendo has been thinking 3d for a long time, but never actually felt that it was the right path for the industry. I wonder if that same tech is hidden away within the Wii. Thanks to Cypher for the heads up!
