Forum:Who are the new characters in the upcoming arc..??

I don't have any information about does new people. But when i read the spoiler at youtube, silentdon place there picture before the spoiler of the manga began. I noticed the three of them, one is a girl who looks like soifon's suzumebachi, the other is a huge guy with a huge flail just like omaeda, another is a guy who looks like yumichika with a feather wings. Do you think the new arc is about the spirit of a zanpakutou??
