I think that Ichigo will have to go back to the royal realm to fix his bankai. If that is the case he will need an oken. My guess is that Ururu will turn out to be the oken that Yoruichi and Urahara wear told to guard by the soul king. The only other option that I can see is for him to go to the Dangai to repeat his FGT training. Either would be great, because it will mean that we will get to see Zangetsu. I guess another option would be for him to go to see Ryuken to get trained with quincy powers.
