I think the most popular theory behind the meaning of "Duodecim" is that it is the 12th war; Dissidia was the 13th. If so, it would mean that Chaos' side would win and the proper way to do that is if the Villians have a story mode. I would've liked that in the original Dissidia and am hoping for it in Duodecim. If it is the 12th war they could still give the Heroes a story mode as a "what if" scenario.

I do like that there will be more than 4 new characters - hopefully not 5. I would like some good alternate costumes, maybe a slight re-design? More maps so there is more options.
