Just finished Wolverine #30 and it looks like (to me at least) that Northstar is about to end up in Limbo. He was rescued by Logan and dropped off to SHIELD for deprogramming but it seems it isn't working. At the end of the book Nick Fury is writing a letter to Kitty Pryde in which he lies, saying:
"What else? Oh, yeah. I got your email about Jean-Paul Baurbier (nice, they spell his name wrong ), AKA Northstar, and I'm sorry to say we never recovered his body after he got snatched by the Hand. My sympathies to you and Northstar's friends, but at least they never made a monster outta him like they did with all them other poor saps, right?"
This is overtop a panel showing NS being held in some machine, I assume meant to deprogram him, quite alive and still under the Hand's control. IMO this will mean NS is going to disappear until someone decides they want to use him again. On the positive side it does leave him open to return to AF!
