I said this in the spoiler thread but hopefully this means Ichigo will be losing his hollow abilities or, at the very least, won't use them anymore. Now that I've read this chapter it appears that Zanpakuto!Zangetsu is trying to purge Hollow!Zangetsu from Ichigo. This is basically what I've been wanting for a while now. The best we've seen out of Ichigo has been when he was relying on Zanpakuto!Zangetsu and now that he's been relying on Hollow!Zangetsu he has felt weaker to me.
All I can say is, hopefully this is the end of Vaizard Ichigo and the rebirth of Soul Reaper Ichigo.
