Honestly, they're probably only announcing the costumes and minions the Japanese site stupidly already leaked. Though, characters would be nice.
This game is notorious for leaks. There's a good chance the Japanese site wasn't supposed to post the minions yet. I mean seriously, 95% of all announcements about this game were leaked beforehand one way or the other.
I would LOVE to be wrong. I WANT to be wrong. But it would not surprise me at all if he's just referring to the costumes and minions.
