Yeah, if you think about the timing the chapters were released in... Did anyone read Kubo's spoilers for the last arc? They mentioned that Rangiku's past would be important. Since she became a shinigami way before Hitsugaya, I imagine she would definitely know something about this whole deal with the previous 10th company captain. Fingers crossed that's mentioned soon.
