Viva Piñata Racing
From PinataIsland.info, the Viva Piñata wiki
There have recently been unsubstantiated rumors of a new Xbox 360 game from Rare titled Viva Piñata Racing.
It is believed to be based on Donkey Kong Racing which was a canceled video game for the Nintendo GameCube. Presumably that was to be the sequel to Diddy Kong Racing, but Microsoft's buyout of Rare in 2002 rendered the game vaporware.
Diddy Kong Racing is a go-karting game like the Super Mario Kart series, and also has a distinctive adventure mode.
