I knew old man Yama wasn't going to die in THIS battle. Now that it is over what now? So many possibilities and battles not yet shown. I wouldn't be surprised if the Sternritters' keep fighting or manages to kill another beloved character, I'm looking at you Rose, where are you buddy?

This probably wont happen but I think it would be interesting if the Sternritters' retreat and on their way back they find an caged Ichigo and take him with them. This way instead of Ichigo saving the captains it will be the other way around, plus Ichigo could meet the real Juha Bach if it turns out tall, blonde, and handsome isn't the real Juha either. But that prolly not gonna happen.
This seems like a good time to go back to Hueco Mundo since we now have one mystery solved (Ichigo's unstealable bankai), not to mention a new mystery (The real Juha), and then there is the old mystery (Who the **** is holding a blade to Urahara's neck?)
