What i gathered from the new chapter is that Ichigo's quincy powers have been masquerading as his shinigami powers, and that Hichigo was the real Zangetsu all along. Makes sense, especially when you think back to when Hichigo proclaim that he is Zangetsu when Ichigo asked who he was all those chapters ago. What I don't understand is if the Zangetsu we've known about all along is really a manifestation of his quincy powers, then what does that make Tensa Zangetsu? And what does that make of the events that occurred during the fight with Aizen when Hichigo and "Zangetsu" merged together? Kubo has a lot of explaining to do.
