And to answer your question I'm going to say probably yes.
Well, as stated in the previous "The Blade IS Me" chapter, Ichigo stated that he will no longer ask for help from either Zangetsu or Hollow (white) because now he's come to a realism or understanding to his true potential and power. Meaning that, Ichigo may not necessary need to go into any mode of power, being Shikai or Bankai. And this could obviously be due to his different mixtures of spirit powers (Quincy, Shinigami, Hollow and Human) and Ichigo is accepting himself as the true source of his own power.
Regarding the twin zanpakuto, that could be Kubo's way of symbolizing Ichigo's duality of self by having two, twin swords that balance out his overall power. Remember, this was an issue with Ichigo's powers in the past, even during his previous training sessions.
I disagree, because Kubo already wrote that "Final Getsuga Tenshou" is simply a technique that allows Isshin or Ichigo to become the GT itself. The result of that is losing your shinigami power. In Isshin's case, that would be a great downfall, however, with Ichigo, who's spirit power isn't limited to "shinigami" logic, but goes beyond that, is a different case altogether.
What I'm suggesting is that, based on Zangetsu (or Youthful Ywhach) releasing the Quincy part of Ichigo's power and allowing Ichigo to finally embrace or whatever, his full potential, his powers will work on an entirely different scale than Shinigami, Hollow, Quincy, Fullbringer, etc. Ichigo is indeed "special" as Kubo put it, in that Jump Festa interview way back in 2010.
If he does have a new bankai, that's cool, too. Not hatin' on that either.
If I'll lol very hard if his new bankai gives out slimmer and smaller Zan(s) than the previous one. All his raw power concentrates in a confinement volume of the blades that his blades create theirs own gravitational fields! The blades absorb light such that they are surrounded by darkness along the edges of the swords.
I don't know if someone's already posted something like this, but I had a thought. Ichigo said a while ago that the black GT was an attack created by his inner Hollow. Now Zangetsu taught him the plain GT, but we now know that he was never the face of Ichigo's Shinigami powers, so he only knew them because he and White were once one. So I'm wondering if Getsuga Tensho is actually Ichigo's ability at all.
White was once his own being, who once fought Isshin and IIRC Isshin used GT in that fight. So what if the GT Ichigo has been using was simply White copying the only Shinigami attack he went up against (presumably)? Even the Final GT might be another thing White stole from Isshin just by sampling his power during their fight.
Getsuga Tenshou came from Isshin, not White. The attack just looks different from Isshin versus Ichigo, because Ichigo has the hollow / quincy mixture in his spiritual power is all.
I think honestly, Kubo doesn't make these things that complicated, it's just people are looking for something extra to these things that aren't even there. It's plain as day, regarding Ichigo's power and at this point, it's makes sense as to why, Ichigo's struggled with his powers for so long.
Maybe he'll still use his hollow mask too.
In a way I'm saying GT does come from Isshin, only that Ichigo only has it because White copied it and passed it on, which isn't so incredible considering that GT is nothing more than throwing ones reiatsu around using their sword.
Ichigo high concentration of reishi creates a gravitational vortex that tips the balance Haschwalth.
If we look at it, there are three things i am looking forward to:
1. Ichigo bankai, during the fullbring arc it was mentioned that ichigo is a person who likes to use power as a cloak, i wouldnt be surprised if that is the case with his new bankai. It will be similar but with little bit of artistic changes, maybe some sort of hollowfication
2. blut/volst: if he accepted his quincy part, he might even show us blut and volstanding, which will be interesting to see. what will be his quincy power?
3. Hollow: Gt is a form of cero, but i wouldnt be surprised that in bankai form he no longer needs a sword to shoot GT
His old bankai had his own piece of clothe though, I think that already fit into the wearing your power thing. Since getting a new sword is not something that should have changed ichigo's overall abilities then I would think that it is a given that he will retain clothes. He got a new asauchi, not a new set of abilities. What should result in some change is the fact that old man zangetsu is not suppressing his powers anymore however I have trouble imagining ichigo showing a significant deviation from what we have seen. Perhaps we can talk about his old zampakuto functions being split. One will handle the GT and whatever other new property it might have (cero fire or something perhaps?) and then the other one will focus on speed. No zampakuto is supposed to have two abilities yet ichigo had one so perhaps speed in itself was always something that came from old man zangetsu rather than zangetsu.
Ichigo has already used blutz. And he should have all the other generic quincy abilities.... I can't wait to see bankai + blut artery though, it should be quite effective. As far as volstandig, I don't think we will see one from ichigo. For one thing, the ster riter could not use bankai and volstandig. I think ichigo will have a similar deal to them. For another, volstandig is not an innate quincy ability nor is it something that can be learned. Volstandig is induced by an object the quincy carry and so was the lets stilt. There is no reason for ichigo to have the proper tool to actually use volstandig. Perhaps given ichigo's growth rate it is plausible he simply does not need volstandig and he can simply use the ability to absorb reishi to the maximum plausible on his own. Hollows seem to have their own way to absorb reishi so perhaps ichigo being part hollow and part quincy will enjoy some synergy.
I think it is entirely plausible ichigo will be able to use normal cero at a point although IMO his actual power is to use cero like energy in a similar fashion to what ishin does with fire. Using GT without his zampakuto does not make sense, GT is a specific zampakuto ability. Its about as likely as ishin using GT without his sword.
If Ichigo can use Vollstandig, then cero is shot either though his clothes or wings behind his back, I've always admired how Stark shot out his cero like an easy walk in a nice park. It would be interesting if Ichigo can compress his Zans down to the size of a paper knife, the destructive power must be over the top.
