Well this news doesn't surprise me because I knew the game would be hot but here it is for everyone else.
Twilight Princess surpasses the 4 million markAccording to all the sales data it gets broken down like this.
Wii version - 3.08 million
North America - 1.55 million
Japan - 560,000
Europe - 970,000
Gamecube version - 1.17 million
North America - 850,000
Japan - 40,000
Europe - 280,000
Both versions total - 4.25 million
Here's the lifetime sales for the other Zelda's to surpass 4 million
Ocarina of Time - 7.60 million
Legend of Zelda (Original) - 6.51 million
Link to the Past - 4.61 million
Adventures of Link - 4.38 million
Wind Waker - 4.35 million
So when you see this Twilight Princess will easily surpass Link to the Past, Adventures of Link and Wind Waker this year. But when you look at the attachment rate and how well the game is selling, the chances are really good that Twilight Princess will actually surpass Ocarina of Time and the Original over the next several years and become the best selling Zelda.
And when the next Zelda for the Wii wont be out until at least 2009, I dont see sales slowing down anytime soon.
