Disgaea 2: Cursed Memories will hit PSP next year.

Japanese-based developer Nippon Ichi sent out a press release late last week announcing that Disgaea 2: Cursed Memories is heading to PSP next year.

An enhanced port of the PS2 original, the portable version of Disgaea 2 will boast extra story content - a rather substantial 30 percent, along with additional characters.

Disgaea 2: Cursed Memories is slated for a March 26 release in Japan. No word yet on if it’ll make its way stateside, but we’d honestly be surprised if Nippon’s publishing partner NIS America skips on localizing this one, seeing as the franchise as a whole has been quite successful on PSP.
This Digaea is in version Japan language, but don't break down your hope that english version will come out not far from Japan language version.
