By big three I mean Bleach,One Piece, and Naruto Shipuuden.
For both series we can safely say that the climax draws near, the question is which one goes first? Personally I think BLeach only because there is not a whole lot they can do right now other than have Aizen make another team or something, I mean sure the whole thing with all the captain not having shown their bankai's and their conditions after the fight (Jushio Uketake) and there has not been nearly enoguh Komamura screen time lol but other than that I don't see a whole lot they can do with the series after Ichigo fights Aizen, which that itself may be dragged on for twenty chapters lol. And there are some rivalries with a few captains (Kenpachi Zaraki vs Byakuya Kuchiki) that I want to see settled, however how it is going now I feel after a few flashbacks and dragged out fights Bleach will finally come to an end.
Now next I see One Piece going only because like Bleach the end is coming now the only badguys are Blackbeard,the rest of the shichibukai and the three admirals however there are the rest of the 11 supernovas and we have no even seen who the other two Yankou (Kaidou and Big mom) but with that said there is not a whole lot getting in Luffy's way after he gets back with his crew, however I do hope everyone in Luffy's crew gets a final showdown with members of the SHichibukai, a few admirals and ultimately the Blackbeard pirates, not only that but a few backstories on some characters are needed and how some people got their fruits (How Blackbeard gave Shanks those scars over his left eye)
And finally Naruto I say this because there are A LOT of things that need to be done like for example who are the rest of the seven swordsmen of the mist? What about Kabuto/Orochimaru and him bringing back members of the akasuki, Zetsu still has not shown what he can do yet (Honestly I think Masashi Kishimoto is going to make him crazy, like stronger than Kisame crazy.) Naruto still needs to master his new form and Sasuke still needs to recover even after that epic showdown the whole Madara thing still needs to be addressed (Epic team-up Naruto and Sasuke vs Madara Uchiha and they win using Chidorisengan lol) Naruto still has not become Hokage, Karin and Sakura have not had their awesome epic catfight showdown. Also non of the supporting cast (Rock lee,Neji, Tenten, CHoji, ino ect really did anything) Naruto has still not confronted HInata about her confession to him the leaf village STILL has not found ot that Baki killed Hayate (My favorite character >O) and so much more (Feel free to add on to anything I missed in either of the three catagories)
So now, what is YOUR opinion on which will end first?
