Apparently selling four million copies in Japan did something to impress Nintendo, as the company announces it will be publishing Dragon Quest IX: Sentinels of the Starry Skies in North America.
Nintendo and Square-Enix have entered into a "unique partnership," in which Nintendo will handle publishing duties on the DS title when it hits sometime this summer. While no distinct reason was given for the agreement, I speculate it has something to do with the more than 4.14 million copies Square-Enix moved in its native land.
The announcement was made today during the opening of the Nintendo Summit event in San Francisco. Look for more news as well as hands-on impressions from the summit as the day progresses.
