I was little surprised about Ichigo's mother being a quincy. That kind of information is just too big to keep a secret for so long. It makes it ever harder to believe when you look at the past. In Ichigo's flashback of his mother's death it is said that Ichigo saw that little ghost girl by the river and Masaki couldn't see her, which is strange because if she is a quincy she should be able to see her too. Furthermore she died by a mere hollow, which means she is either very weak or she lost her powers just like Uryuu did.
We sure need more information about her in the future chapters. I believe Kubo was intentionally keeping Masaki's past a secret so he could fill it up whatever he feels like.
Overall this new information makes Ichigo a human who is half shinigami-half quincy that can use fullbring and hollow powers.
I can't wait for Ichigo to develope his Geass, his vectores (Elfen Lied) and his stand (JoJo's BA).
