According to a recent CBR chat with Mike Carey, Northstar will be appearing in X-Men #189 and #190. He is described as being "in a very dark and strange place, psychologically - far from recovered from what the Hand did to him."
Further, "Aurora will also figure in these events."
Also, "Northstar is in #189 and #190, and after that he won't be seen for a while. But we kind of move him on to a new point, and he will be back."
So lots of new questions about where all of this will take our favorite French Canadian. Hmm... I really want him to land in a regular book somewhere.
