I wouldn't count on it.

Ulqi said that Aizen doesn't know about it. which means that Ulqi has been keeping this a secret. who's to say that Starrk, brannagn and bigboobsninja aren't hiding the same thing? maybe it's just that Aizen doesn't trust Ulqi enough to let him into his secret club of awesome hollows? (Ulqi defintally had too much screen time to die now, he's going to show up like Byakuya does).

also, how did Rukia get into the Zanpatsou poll?
