Robin in Dark Knight Rises?

Rumors were rampant this weekend that Robin will be making an appearance in the new Dark Knight Rises. Pictures have already been released showing the completed Bat Cave inside the rebuilt Wayne Manor and now rumors have popped up that Joseph Gordon Leavitt will be our Robin. It's been confirmed that JGL is casted but only as 'Beat Cop'. Why would an A-List actor be in a bit part? iheartchaos has the details.....

".... a weapons prop crew member was in the shop talking about the filming, and said thatROBIN WAS BEING INTRODUCED IN THIS FILM.
I repeat, he said that ROBIN WAS BEING INTRODUCED IN THIS FILM.
I asked him who he said would be playing him, and he said, “The dark-haired guy from 3rd Rock From the Sun.”
That, of course, is Joseph Gordon-Levitt"

That's just a snippet of this rumor that's been posted at NerdBlasters and iheartchaos. My feeling are mixed too, Nolan has dominated the last couple films and managed breath new life back into a dead franchise. I have faith that he would do it justice and not make the new Robin out to be the ambiguously gay sidekick he's been portrayed as.
