@ AceAlpha:I agree that Zoro has to get stronger to defeat (or even touch) Hawkeyes, but I disagree on the gap between the swords. The black sword may be the strongest sword, but I think in the end it will be the power/will behind Wado Ichimonji (the straight path of harmony) that will help him defeat Hawkeyes in the end. Afterall, it is Zoro's will to become the greatest swordsman in the world that drives him, and it was Wado Ichimonji that was given to him to take him there.
As for his other 2 swords (Yubashiri and Sandai Kitetsu), I don't think they'll make it. Although I wouldn't be surpirsed if the Demon Splitter turned out to be a very powerful sword (even though it isn't one of the world masterpiece swords or w/e).
Bottom line, he doesn't need some elephant sword/devil fruit to defeat Hawkeyes IMO. I think he'll blow away Spandam and that stupid sword with his three (or maybe just Wado Ichimonji).
