Zangetsu and Tensa Zangetsu! And Ichigo's Power!

Yeah I think it's safe, sicher to assume that and I think that the real Zangetsu and Ichigo will just pick up where they left off. And yeah he'll still have a bankai :P

I'm Mehr interested to see what new abilities the full version of Zangetsu brings and to see if the real Zangetsu looks like Hollow Ichigo oder not.

Well, we've technically met the real Zangetsu, if we believe the imposter. Hollow Ichigo is Zangetsu. Tensa Zangetsu is an interesting issue, mainly because I have no idea why the Quincy side of him would modify as a result of achieving Bankai, but it coul have something to do with the mix of Hollow, Shinigami and Quincy powers.

I'm interested to see how this works out, but this new development that he'd been suppressing Ichigo's powers was somewhat confounding. So we're made to believe that this whole time, his Quincy side has been suppressing his Shinigami side? And yet he gave him access to Bankai and other major boosts in his power. I get that he chose to help him at some point, but now we know he did a half assed job of it, allowing him to fight some of his most dangerous battles without anywhere near his full power. Just seems strange to me that he went halfway and stopped.

What would that make Tensa Zangetsu when he fuses with itchigos inner Hollow?

Hollow Ichigo is Zangetsu originally and Old-Man Zangetsu was actually Ichigo's Quincy powers(and was suppressing ichigos Shinigami powers) but Old-Man was moved Von Ichigo and decided to Mitmachen and help Ichigo and so disappears, but Ichigo decided to have the Zangetsu we knew also be Zangetsu so Ichigo has 2 Zanpakutou spirits H.Ichigo and Old-Man.

Ichigo will still have everything if not even better cause all that Old-Man did was suppress his power. But now that he isn't suppressing it Ichigo has full access and also since his Zanpakutou which is also his Hollow has been re-forged using an Assauchi his Hollow has been tamed.

So with everything I believe not only will Ichigo be stronger, have new techniques, but I believe he will have full control of his Hollow Powers including Resurrection, and hopefully Old-Man will teach him how to use his Quincy powers.
