According to the official website, the North American release of New Super
Mario Bros. has been pushed back to May 21 (Sunday). The title will likely show up in stores early that week,
quite possibly, alongside the new DS Lite. Indeed, 1UP speculates that the game was delayed in order to accompany the
launch of the DS Lite in North America. It wouldn't be the first time Nintendo deployed the plumbers to help move new
(or updated) system units — and if true, it won't be the last.
