I disagree. Tim isn't going to get a new identity Damian is.
The comment from Bendis is a clue. Tim just got re-branded with a new look. They are not going to change it yet again. Not a wise move.
They already tried to change Tim [from sidekick to independent hero] and that failed. Change isn't good for his character like it was for the 1st two. He was designed to be Robin. That's what he is and like others have said it's all he wanted to be.
Damian will graduate [hopefully successfully like Dick and Jason] with a new look and a new id. I expect he is also about to be aged up.
Can't wait to see the new look and id. I've got so many directions come to mind. [fingers crossed] Bruce gets his happily ever after with Selina. Damian becomes Batman with Robin Tim
It's a long wait till the end of King's Batman when the restructure happens.
On the upside we are in for some exciting stories which should make the time fly.
DC comics bout to get interesting once again.
