And may be aizen is going to sacrifice all the shinigami captains and the espadas that r in ichigo village instead of the people coz they have more power which will allow him to create the key without needing to kill the useless people i think that may be his plan.
No Aizen won't sacrifice anyone there. Basically I think he is just stalling for time. No one is in soul society. He could just use that instead, right? I mean, all of the important characters of bleach are either in the town or Hueco Mondo right now. If you think about it, it really makes sense. That is unless I forgot about a rule or something to make the seal.
