The article also says that DD2 is a new series separate from the main numbered series. Whether this means more adventures for the Disgaea trio or letting Adell, Mao, or Val have another go is unknown but regardless this is all kinds of awesome.

UPDATE (Thanks maharl)
A new siliconera article says that Dimensions will introduces new characters to the story. One of them, who is in the group shot, is Laharl's ????????

There are also rumors of monster mounts.

UPDATE 2: (Thanks nalina)
http://disgaea.jp/d2/

The background has changed to the group artwork but with everyone shadowed out with the exception of Laharl. Most likely, the others will become visible as we count down to when the official site goes live. There's also a new BGM.

could also be dlc for the other games though (as in dlc for the sequel of 2,3,4)

maybe after all this we'll finally get another shot at a disgaea anime
