CONFIRMED!!!!!!!

The Dark Knight's butler, British old timer Michael Caine, said this at the Toronto Film Festival...

"I was with [a Warner Bros.] executive and I said, ‘Are we going to make another one?’ They said yeah. I said, ‘How the hell are we going to top Heath? And he says ‘I’ll tell you how you top Heath — Johnny Depp as The Riddler and Philip Seymour Hoffman as The Penguin.’ I said, ‘S–t, they’ve done it again!’”

I think that's a confirmation.... wahoo, so stoked! Johnny, I'll play with you if you wanna riddle me! haha
