Higgins just tweeted (in the last few minutes) with regard to the Death of the Family arcs.
"Nightwing doesn't HAVE to be Dick Grayson, right :)" and "I mean it IS called Death of the Family #nothingtoseehere"
Is Higgins trying to fool us all or is he hinting at what might happen in the storyline?
He does have a point, the name of the arc suggests someone will die. Although saying that I'm hoping that the title is meant to mislead us and that actually the family dynamic of the Bat-family will 'die' rather than any member of the group.
