It seems that it's the definitive one, since in the dates matters - I believe in GameFAQs.
The Legend of Zelda: Twilight Princess Nintendo 08/25/06 EU
The Legend of Zelda: Twilight Princess Nintendo Q3 2006 US
Zelda no Densetsu: Tasogare no Himegimi Nintendo TBA 2006 JP
Great news for Europe, if this is true (Which I'm 80% sure), I'm gonna have great-great summer holidays ;D
