This is how I imagine things will pan out in bleach.
Aizen will make his key into the kings realm dimension shit and go attempt at taking over the world.
Orihime can somehow manage to break into the place using her powers, because she's able to detect the barrier and shit... but has to stay behind or whatever.
8 volume arc on fightings
Aizen dies and Ichigo and Co get the fuck out and bleach ends.
