Disgaea 4: The Promise Unforgotten

Hopefully this will skip over the mediocrity of 3 and be as awesome as 2 was, again.

I won't lie, D2 is my favorite Disgaea game, but I really doubt they'll go backwards in the game mechanics for D4, if that's what you even meant in the first place.
I'm really interested in seeing how they can break the game even more though, since D3 pretty much destroyed it when you could hit 1.17 Quadrillion damage.
