The Japanese publication NINTENDO DREAM has recently confirmed with Nintendo Company Limited that the first GameCube Mario game will be released next year. This marks the first time that a Mario title has not released with a Nintendo console's launch.
While there have been some rumors regarding a top secret Mario title due at launch, it now appears that this is highly unlikely. Some other reports from Japan indicate that the new Mario title could be released fairly early in the year.
More on this as it breaks at Nintendo's SPACEWORLD conference.
