lol you guys do realize that Tite Kubo said in an interview that he didn't know who Aizen's murderer was during the SS Arc right? Do you think he planned ahead Ichigo being a Quincy since then?

The way Mangakas work, they have to finish one chapter per week. They sleep 4 hours a day and work 7 days a week. They usually don't have time to plan things out that far in advance and Bleach was originally supposed to end right after the SS arc.
