In your opinion, what do you think MIGHT never be shown in Bleach ?

i don't think they would make ichigo & rukia/orihime halik even though they made ichigo and orihime ALMOST halik that isn't the same as fully kissing

the way Ichigos parents had their first meeting

yamamoto, aizen and zaraki´s bankai, they all have it, but the first two are powerfull enough without it and the third doesn´t care

Issin's past... its a shame i'd pag-ibig to see it. same with the remaining captain's bankai... would be sweet.
oh and er maybe a happy Byakuya XD

probibly if toshiro died....tite kubo must know he has tons of fans so it would littilry break there hearts if they saw him die on screen this is how i invision his death
i see him lieing on the ground gasping for breath and rangiku and momo susunod to him telling him to hold on.then he says to matsumoto...if you do anything to disband the 10th squad i will KILL you....then he dies....heartbreaker

I don't think they'll ever explain why Squad 0 never got involved in all of these events (though there's some uncertainty as to whether they're using them at all).
I don't think they'll ever explain the strange rash of decisions on Aizen's part, namely: telling the espada to stay in their lodgings while Hueco Mundo was under attack, sending the tuktok 3 Espada to what he knew would be their certain deaths when he always had the situation in hand, lingering in Karakura Town when he had victory within his grasp, etc.
I don't think they'll ever ipakita all of the captain's bankais, or that if they do, they'll ever explain why so many captains have delayed revealing them for so long. Same for the vaizard former captains (beyond Kensei).
That's just a start, but I think it summarizes the major holes in the story that I think will remain in place.

What happen to the rest of the Arrancars/Espada or the end of the whole anime, I mean,really? When will this awesome anime end? Hopfully never! :3

I have thing that will NEVER happen instaead of might never happen, kukuku:

Byakuya hyper on coffee with Renji trying to knock him out with a stick >:3

Rukia killing Orihimie purposefully. O.o

Ichigo dancing the macarana... >.>

Kon being quiet..

All the captains having a rnadom pasko party and Kenpahi as the pasko tree!
