Oh come on... toned down with this fight? censored because its licensed in USA?
heck... this series has been toned down from the very beginning.

Jidanbou didn't lose an arm. Kukaku didn't walked around without her arm, but with a prothesis (sp?).
You can't think the series just got toned down now.

Bleach, like many other Shounen series (Naruto), get aired at prime time, or at least at hours with a lot of audience. Tv everywhere has censorship. It is not recent, its being around since episode 1.

A bit of blood can be shown freely, but not impalements, lose of limbs etc. They just add it when it is absolutely neccesary.
