Before Kubo started this arc, he did a little...let call it a preview; it was put on here so you may have read it. In case you haven't he gave a few teasers about how the plot was going to develop, and the main cast all got some extra details; in Kira's case he mentioned something about Bankai. It wasn't an explicit statement that he had it, but I think that the fact that he put it in an official press release says he has something planned for Kira in the future.
