I do expect that he won't use it until he faces off against Yhwach, yes.

I also think that the Bankai will have the same name. Zangetsu is still the same Zanpakuto and has the same spirit, the only difference is that it was forged with an Asauchi which it never had.

As for the appearance, I expect a similar appearance to his old Bankai, with certain changes, it might even become 2 separate blades in Banai as well for all we know. As for abilities, I wouldn't be surprised if it still grants him great speed at least for one of the abilities, but I don't really think about it.
