@Yyp, oh, my apologies. Thinking about there's probably some ritual that he has to perform to create the Oken, right? Maybe that's what will take so long. Him finding the proper location, talk to Gin about what he's going to do, prepare and then execute. I do like the idea that Aizen would wait until Ichigo shows up just to show him how futile his efforts are and then start to perform said ritual. Kind of like "I waited until you showed up so I could look into your eyes and see your face as I destroy your home and the people you love.... And there's nothing that you can do about it"
