After the closing reveal of The Dark Knight Rises, many moviegoers (and media members), began hammering Levitt for answers about a possible sequel featuring the John Blake character. The actor quickly dismissed talk of a follow-up – claiming that the studio had not approached him about it and that, for him, reprising the role would be dependent on the quality of the script.
As mentioned in an interview with MTV, Levitt also dismissed the notion that Nolan had a particular alter-ego in mind for the character, asserting that they never talked about which “suit” the character might wear:
However, even if we never see Levitt fighting criminals on the streets of Gotham again, that doesn’t mean that fans aren’t interested in some closure about which fan-favorite Batman character he had been playing all along. Many enthusiasts argued that the reveal of the character’s first name, Robin (as in Robin John Blake), was a dead giveaway for the boy wonder (Dick Grayson); others felt as if Nightwing, despite the obvious nod to Batman’s most famous sidekick, would be a much better fit for Nolan’s universe. In the comic storylines, Robin (still Grayson) becomes Nightwing – taking on the persona as he matures. Similarly, Blake could have easily just become the new Batman – just like Grayson did (again) in the DC universe.

It’s a theme that Levitt himself discussed when talking about a possible John Blake sequel on Jimmy Kimmel Live:
