It is still fused with Aizen from what i know, and yes it very well could. The newest chapter has Head Captain, Captain-Commander, Shunsui Kyoraku down in Muken about to have a conversation with Aizen. So likely it will show up. Which side will it be used for though, if used at all, is any ones guess.
