So, whatever the case, this must be Aizen's end (otherwise we're in for a really crazy big damn heroes #4329587 moment, should Aizen survive the attack...). Anyway, might as well end bleach here, or turn it into a slice of life comedy
On second thought, if Aizen dies here...
1) What happens to poor Yammy?
2) We'll never know how he lurked during Ichigo's entire life.
3) We won't see his bankai, obviously.
4) So much for Shinji's revenge...
