Well the evidence points to it being true!
Dick Grayson! The FIRST Robin is one of the most loved comic book characters of all time. A guy who's made so many transitions, yet still manages to receive even more adoration from fans of DC Comics, and even trusted by the mighty Superman himself.

As previously announced, Dick Grayson will be the main character of Titans. However, he will still be Robin at the beginning, though the switch to Nightwing could happen later on. After quitting as Batman’s sidekick, this version of Dick is now working as a detective in Boston. The article points out the similarity in career path with Chuck Dixon’s 1990s run of Nightwing, where he became a police officer in Bludhaven. Given that Titans will be featuring the heroes in their twenties as opposed to being teens, it’s likely that Dick will exchange the green tights for the black and (ideally) blue Nightwing costume.
