Disgaea 3's been announced! Yay!
For PS3! Boo!
Next year! Boooooo!
The details are in this pdf that's on the Nikkei website. (Yes, the Nikkei as in Japanese stock exchange...! I don't remember ever hearing about any new games this way before!)
I think I'd prefer the game to be on PSP. Not just because I don't own a PS3, but because I appreciated the portability and sleep mode of the PSP version...
