The game just came out in Japan earlier this month, and Infinite World (the latest fighting game for the franchise, an expansion of the Budokai series) on the PS2 managed to push 76,500 copies in its first week (coming in second only to the latest Professor Layton game, which itself pushed 87,100 copies that week).

As a point of comparison, Dragon Ball DS (release internationally as Dragon Ball: Origins) pushed about 72,000 copies its first week in Japan just this past October, while Burst Limit pushed 92,298 copies on the PS3 alone its first week this past June.
