Can you post or direct me to a pic? I tried Googling, but found various contest-type designs from amateur artists.

For a second I thought you were talking about the Earth-Two Robin (Batman outfit with yellow cape, and Bat insignia with Robin's "R" on top) in which case both that costume and the more well know yellow long-johns look are long overdue from Matty.

As for blaming Christopher Nolan, Jim Lee should take all the blame for the horrid design. He should be designing gym clothes rather than superhero costumes.

Here ya go:
Don't get me wrong, I love all three Nolan films, but mark my words-- Warner is going to look at almost all their superheroes going forward through the "grim n' gritty, real-world approach" lenses. And that's fine for stuff like Batman and Watchmen, but not for everything. Anyways-- I'd happily take an Earth-2 DG in either his half-cowled Robin costume or his "bat" suit, as well as a disco Nightwing for sure. But I want a DCUC-styled and scaled Batman and Damien first and foremost. But, knowing Mattel and DCD, we'll get the red Nightwing outfit before any of those.

I feel exactly the same way about most superhero costume redesigns these days-- too many of them are overthought, especially for the movies. The newest Spidey costume looks like it needs a Nike or Adidas logo somewhere, for instance. Sigh...

I'm with you. I'm dying for a Dick Grayson Batman. I'm astounded we didn't get one yet from Mattel or DC.
