He was shot in the head in the Batman title and lost his memory. This messed up whatever plans Percy had for a long run and he left the book. Right now, I think Lobdell is writing it, and I guess Dick homeless and refuses to have anything to do with the family (Im not reading it so this is just what I hear). Oh, and he's going by "Ric" now.
You can *do* that??
Can we add Nightwing to that list too?
Actually, if anyone talks to Bendis on twitter, ask him if he's a fan of Nightwing. I'd happily see the character in Bendis' hands right now, unless Morrison, Snyder, or Johns (or someone else who gets free rein at DC) is interested.
