The dark knight rises anyone please?

so here's the thing i heard some rumors says that joker will comeback in the new batman movie i don't know if it's true and i'll be shocked if it's true cuz i don't really think that someone can match what heath ledger (R.I.P.) did in the dark knight but anyway does anyone have some information about it i mean the joker is the rumor true and if it is who will replace him in the movie i'll apperciate it thank you (it might be one actor in the world that can replace him and it's johnny depp )
