I agree with less filler and not go down the route of Naruto

which just prolonged the original idea, imao was a decision that the director took to try and keep the audience to continue watching but failed

and lost the auidence before it could continue with the original idea. In the case of Bleach there was the bount arc however the creators did a good job by having an interesting concept and began the new arc before the audience was not interested

.I believe that bleach is going into a filler stage now since its near the end of the year with some sort of year special but they may decide to leave audience on a cliffhanger with an epic episode, wonder what are chances of them doing that?
Edit: @timewiz

Considering the story now with your input the likelyness of Aizen in a new arc are high but my theory now is that he is likely successful with his plans and the heroes chases after him to that heaven thing. Also the hoyuko (spelling

) wont be destroyed , to make that key thing. However do you think they should just have ichigo kill Aizen since Ichigo's powers are still a mystery and that would be the end of Aizen

?
