Caped Crusader is another name for Batman, yes. But Dark Knight Rises actually seems like it'll have something to do with the theme
of the movie. Just like the Dark Knight in the last movie got to have that Harvey Dent symbolism (the White Knight/Dark Knight thing). He's the caped crusader because he constantly fights for justice and, err, he has a cape. Yes, it's less repetitive, but it doesn't add anything else.
