With 2.3 million copies sold in its first week, Dragon Quest IX is already a smash hit. Square Enix shipped 3 million copies at launch to ensure everyone who wanted the game could purchase it.

But Square Enix isn't stopping there.

Square Enix president Yoichi Wada told the Japanese press, "We're look at reaching over 5 million copies of Dragon Quest IX shipped." Wada went on to say that he hopes this will correspond to breathing life into the entire Japanese game industry.

In spring 2008, the exec hinted that it was possible to ship ten million copies of DQIX.
