A recent quote from Steven Blum on the Narutofan forums:
p.s. Can't audition for Bleach. They went non-union.
NO! Not only does this mean my fantasy of Blum playing Urahara probably will not come true, it also means that it's very likely Bleach will be dubbed by the Ocean Group in Vancouver. Those are the guys behind the Inuyasha dub (which I don't particularly like).

This could be a good thing or a bad thing. For me, no Blum = a bad thing. Damn.
