Sony's long-delayed racing game Gran Turismo 4 was finally released in Japan. A North American release is pending.

Gran Turismo 4 is off to a strong start in Japan, with about 635,000 units of its initial 1 million unit shipment sold through in its first week at retail despite being delayed past Christmas. The game was pushed back to Dec. 28 at the last minute - a change which didn't seem to dampened enthusiasm for the popular racing franchise.

The 635,000 sales figure means that Gran Turismo 4 is selling faster than its predecessor, Gran Turismo 3, which sold around 620,000 units in its first week on shelves in Japan.
