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.

So the "Dimension" Disgaeas could become a series of sequels to the normal Disgaeas? I like the idea as long as they don't make them very often, I mean there are just 4 Disgaeas right now lol.

By the way more info from here: http://gematsu.com/2012/10/nippon-ichi-software-talks-disgaea-d2 (http://gematsu.com/2012/10/nippon-ichi-software-talks-disgaea-d2)
Disgaea D2 is a continuation of the first Disgaea, set several years after the good ending. It stars Laharl, the main character of the first game, as well as Etna and Flonne. Old characters will return and new characters will be introduced. The game will have the familiar slapstick, yet serious ambiance Disgaea titles are known to offer. A remake of the first game was considered, but the team wanted to deliver a new story.

The game system will focus on the good points from Disgaea: Hour of Darkness and Disgaea 4: A Promise Unforgotten. But since many fans believed Disgaea 4‘s system had too much volume, it’s being balanced to be closer to the original Disgaea. Disgaea‘s system is popular, said Kozakai, but there is an impression of weak spots in the story, which the team aims to repair. In terms of new elements, there are still various features that have yet to be revealed. It appears you might even be able to use monsters as mounts.

This is all kinds of awesome, but now I am afraid there will be too much Disgaea, hope try some new gameplay variants to keep it fresh, the Disgaea spin offs like the Prinny games were just as fun as any other game NIS have made IMO.

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

New character teased: http://www.siliconera.com/2012/10/24/disgaea-dimension-2-character-teased-might-have-monster-mounts/
"the magazine teases one of them is Laharl’s ?????"

At first I thought nothing of it, but now one of the commenters at siliconera seems to think it looks like Laharl's mother, and I really excited! Must not get my hopes up... must not get my hopes up!!!

...I know. Jen, why were you wasting time in photoshop to do this.... He's gone from being around 4 heads tall to 5 heads tall. He's 5 heads in the summer greeting too. I glanced through the old artbook too.. he was pretty consistently 4 heads... So. Yeah. I wager we actually have a fairly large time skip ahead of us..... or he had a quite a growth spurt. |Da

But given this is Disgaea, goodness only knows what age they're going to be setting them to. Looks don't really help. lol

ALSO the Prinny blog updated with a bit about the site: http://ameblo.jp/disgaea/entry-11388178592.html Yeah sounds like it will be progressively changing. So hopefully we'll have a HD shot of miss new angel soon. XD
