I can't even imagine what Ichigo's new Zanpaktou will be. I'm really hoping he will go dual wield mode, the power of Zangetsu in one and the power of the Hollow on the other. But there are already two dual wielders in the story and it doesn't kinda fit Ichigo's personality.
@Gallahadd, I kinda like the plain feel/style of Zangetsu over the other more flashier Zanpaktous. The only one I might take over Zangetsu is Fujikuzyaku, only because it's cool looks and the fact it's kidou based Zanpaktou.
