Square Enix expects to ship 5 million copies of Dragon Quest IX

Last week, Square Enix president Yoichi Wada gave a statement to Japanese press that helps illustrate the company's (justifiable) sales expectation for
Dragon Quest IX. "We're looking at reaching over 5 million copies of
Dragon Quest IX shipped," he said, as translated by
Kotaku. With three million shipped in the game's first week, 2.3 million of which sold right away, five million seems
conservative, and we can only assume Wada is referring only to shipments in
Japan.
Somewhat less conservative is the forecast Wada made last year, of
ten million units. While we have absolutely no doubt
DQIX will break a record or two in Japan with the combination of
Dragon Quest-level initial sales and DS-style longterm sales, that
still seems optimistic.
