It's been stated by Kubo that it will be the final arc. But he said it would be ranging from 4-5 years.
Kubo does not have that much money & support to hold it for that many years.
The people over in Japan are financially supporting other retarded mangas such as Ass class, Sket dance & etc. over Bleach.
It is the most ridiculous selection ever and the worst part is that more than half the income generated by Kubo is coming from Japan...
The manga will be their prolly until the end of 2013. If he really did have 4-5 years then he would not be rushing through the series as he is doing now (Byakuya dying like nothing, Yammamoto dying with no clear background).
PS: remember back in 2009 when Kubo said that he has enough material to keep Bleach ongoing for 10 years? Well...thanks to fillers and weird arc's such as fullbring, his decision has changed.
Main Point: Don't trust what the author says!
