Tim Drake is one of those characters that jumped off the page from the moment he was created. A deliberate choice was made to make him a reflection of the intellectual elements of Batman's story, and to make him a character without the pathos that permeates a lot of the Batman universe. He was clever, engaging, and experienced nearly constant character growth for twenty continual years of publication. Not even Dick Grayson has been able to maintain a book for that long.
We've kept his story almost completely intact, up until a point. The decision to have Tim move on from his Robin identity to make room for Damian was a good one; as long as Tim has been Robin there was always a sense that he was destined for bigger things. He had no intention of becoming Batman, but he was always going to adopt a new, more personal persona just like Dick Grayson had before him. The decision to make him Red Robin was coming from that idea, so it certainly wasn't a bad idea in theory. The problem came from the fact that the name Red Robin and the corresponding costume were ridiculous. People love Kingdom Come, but it's a self-contained story and the designs for it really have no business disseminating into the continuity proper. The costume redesign for the New 52 was considerably better, so we've adopted that, and also downright stolen the name from another New 52 character, Talon. It's actually an excellent fit for this costume, and works quite well with Tim's new dynamic. (There's even a small amount of precedent for it, as Talon is also the name of the sidekick to Owlman, Batman's Earth-3 Crime Syndicate doppelganger.)
We've altered the Death of Batman slightly, making it about Bruce's year in captivity by the League of Assassins. This means that the year Tim spends searching for him and developing his new identity is a globe-trotting adventure that leads him to interact with many characters, not the least of which is Damian himself. That Tim and Dick work TOGETHER to bring Damian into the bat family really strengthens the fact that they are all brothers, and we really think that fact alone makes any change to their stories worth it.
