In the manga chapter 162 when Ichigo is first using his bankai in a fight against Byakuya, Byakuya begins explaining about the importance of a bankai. He comments on how only high level soul reapers, and a single child every several generations in one of the 4 noble house holds. after this he says that "its almost as if...". My question is -

Does anyone know what Byakuya was speculating during this interaction?
