Nintendo's GameCube version of The Legend of Zelda: Twilight Princess won't ship concurrently with the launch of the Wii - in America at least.
It has been delayed, but the news isn't all that bad: it will reach the US on December 11 (a fortnight after the Wii's launch). Given that the Wii is launching in the UK on December 8, that would appear to make it a bit touch-and-go as to whether Twilight Princess for the GameCube will make it into the shops in time for Christmas on these shores.
