I'd like to hope that Unohana is still alive. I'm hoping that in a best case scenario, she'll have gotten rid of the Yachiru Unohana persona (after all, there can be only one Kenpachi, because I guess it's like Highlander) for good, and just let herself be Retsu Unohana for the rest of her existence, if that makes sense.

As for Kenny's shikai, I feel like it's going to change shape to some level along the same lines as Ichigo's did once he learned the name of it; remember that when he was just borrowing Rukia's power, he used an oversized, western-esque broadsword, but after he spoke to "Zangetsu," the sword he wielded because more katana-like in shape and style.
