It's not even released outside of Japan yet, but Nippon Ichi has been steadily planning Disgaea 3
expansions for consumption. While these updates and such may just be for Japan, it's likely we'll either see them incorporated into our game from the start or will see them on the PlayStation Store shortly after the game is localized. Anyway, starting June 27, there will be one pack per month until January of 2009
-- contents vary. In June, a new character will be available and sometime in Winter, new scenarios will open up. These aren't free, but only cost the Japanese fans 100 yen per pack. We'll find out in August what'll become of these updates outside of Japan.
