Kubo has strongly hinted that Unohana has something hidden. In interviews he singled out Unohana and Kyoraku has people who were more then they seemed and in Bootlegs he wrote "She rarely has an opportunity to serve on the front line, but her natural offensive abilities are at their peak! Could it be that the most terrifying captain of all is...". But I don't think Unohana is about to fight.

My best guess is that Urahara will make an appearance to take on Wonderweiss OR Kensai might turn-up apologising for letting Wonderweiss get away from him. I mean, I do hope we see something of Kensai's bankai. He releases and then gets defeated off-screen... that's not fun or fair! Some of us were looking forward to see him fight T_T
