Is Robin in The Dark Knight Rises?

Short answer no with a but, long answer no with me rolling on the floor laughing and pointing at you. However this is the internet, where every rumor gets it's 15 minutes, so lets play along.

according to Michigan’s WILX: “They looked at the Ledges as well as a water treatment plant located inside the park. Sources say the area is being considered as a hideout for Batman sidekick Robin.”

“They,” of course, being location scouts for The Dark Knight Rises. This sounds pretty airtight to me, since a well-known part of the Robin mythos is that he lives in a water treatment plant. Is this who Joseph Gordon-Levitt is going to be playing?

So there you are, proof positive that someone heard from someone else that knows Robin is going to be in the Dark Knight Rises.

If by some remote chance they do shoehorn Robin in, I'm hoping it's the Stephanie Brown/Spoiler version. Stephanie Brown kicks ass.
