Nintendo Pennant Chase Baseball [GameCube UNRELEASED!]
27http://www.unseen64.net
"Nintendo Pennant Chase Baseball was a baseball game for the Nintendo GameCube. Originally scheduled for a June 2005 release, it has been delayed indefinitely, and is no longer listed on Nintendo's website.
In April 2006, 2K Sports brought its baseball game MLB 2K6 to the GameCube after several years of not supporting the console. 2K Sports secured 3rd party exclusive use of the Major League Baseball licence, so the only companies that could produce a licenced MLB game for the GameCube were 2K Sports, or Nintendo; it is widely believed that Nintendo Pennant Chase Baseball only existed because of 2K's lack of support for the system, which would add further evidence that this game is cancelled.
According to 1up, this game is a plausible Wii title that could ship sometime in 2007, though nothing has been confirmed." - wikipedia
