Yes we still have the hell arc.
Aizen flees to hell and sells his soul to the devil for fame, fortune, and power.
With the power of screamy death metal (like at the end of Bleach opening 3) and creepy looking bleeding skeleton creatures from hell, Aizen rules the shinigami realm through fear. Years pass and he becomes a near omnipotent being.
Meanwhile, it is revealed that Zangetsu used to be a part of the Seattle rock scene before he became the entity he is now (possibly killed by Courtney Love?) and he forces Ichigo to undergo another training arc where he must learn how to shred like a pro. His zanpakuto will take the form of a flying V guitar and will be able to shoot a new type of energy beams not unlike kidou and cero called "Mother****in' guitar beams, Jesus Christ!".
With the power of alternative rock and grunge, Ichigo sets out to defeat Aizen and put heart back into music.
I think Kubo would agree, don't bother him about it.
