It's just a temporary arc, the guys will be back at the end of it.
I may check it out, but what I've heard suggests this arc is going to last a while. Strikes me as odd to change the name of the comic, makes it a bit harder to track what's going on. I was honestly confused when Ghostbusters stopped showing up in my pulls and when I looked into it I was like, "Huh. Well I don't want to read about characters I don't care about. Well, needed to thin my pulls anyway."
