The director is Takeo Kujiraoka. He was the battle director of Dissidia 012, and a battle planner on the first Dissidia. He says they're planning over 50 characters for the game (including time release updates), and additional costumes for characters as well.
~ Mash and Zeid ~
~ Crushing Exdeath tree ~
~ Taking down all its HP ~
50 characters should mean at least 3 per game, although I'd bet the NES age games will get shafted, but hey, more opportunities for the VI and XI cast.
Looks promising. I like DoA, and I figure Team Ninja should be able to help balance the game in an item-less environment, if that ends up being an option (even if only for the home version) - the item and skill system for the Dissidias was actually pretty interesting.
