Yes, nobody expected Aizen to actually die, but coming out unscathed? He was supposed to pull off something new, to actually show how he is POWER, and not bringing this unsustainable switch, that nobody has been able to explain. On my entry I explained why the switch is absurd, there is no way it could have occurred, Ichigo was watching the whole time and he didn't say a word! And Aizen didn't have a single open moment to perform it.

On the Royal Division, the chances of them appearing are very limited unless Aizen actually reaches the dimension of the king, which will only happen if he can destroy Karakura and create de Oken for which he must destroy the pillars (which is why I suggested Yamamoto could be keeping an eye on them to make sure Ichimaru didn't destroy them while Aizen was swapping the floor with everyone else)
