Via Fraggerock, a video for the upcoming 2D Super Mario Bros. DS game, New Super Mario Bros., has been leaked and has surfaced on YouTube.
The video shows about a minute of leaked footage of New Super Mario Bros. gameplay, featuring some good ol' Super Mario side-scrolling charm, including some new bendy warp pipes. Needless to say, it looks awesome.
New Super Mario Bros. is scheduled for a late 2006/early 2007 release.
