If this game was 2d I'd be extremly excited, but since it's 3d, I'm going to be cautiously optimistic. The thing about Treasure is their gaming gods at 2d games, but hit or miss when it comes to 3d.
Plus the Bleach DS games worked so well because they were based off of Treasures amazing Yu Yu Hakusho fighting game for the Mega Drive (Genesis). The problem with this game now is Treasure has no 3d fighting game from the past they can work off of so we don't know how it'll turn out.
But since it's Treasure I'll remain hopeful since they're a talented team. Plus at the very least it'll turn out decent since even Treasures worst games usually end up being good titles in their own right.
