Yeah I have heard about that one. It's sadly unknown what this means for Cass Cain.
Will she be finally made part of Nu52 or not?
Im not that much into it but did hear a few talking about that there seems to be some agenda going on against her by the higher ups in DC for unknown reasons.
It's funny. I do get the impression that the editors from Marvel are a bit to lax while on the DC side they seem be really overzealous.
