Halibel > Inoue....If you know what i mean(LOL!!!).
My guess is the royal guard will come after this fight and demand that Ichigo follow them to the other dimension given the power lower he has achieved or something like that. IT could be the perfect time for a time skip too.
Given how one piece and naruto have had time skips, i wouldn't be surprised if there's one for bleach.
but if Aizen somehow evolve to something even more powerful than Ichigo then.........
