We know how many were sold in the first two days, and now we also know how many copies of the game were shipped. We sure do know a lot of things.
Rumors that 3 million copies of DQIX would be available at launch in Japan are corrected. Three million copies of the game were shipped. Always nice to have game launches free of "shortages". Everyone who wants a copy should be able to get one at launch — all 2.3 million of them.
