According to Cinematical.com The Dark Knight trailer will be available”in about two weeks”.
Trailer looks great, lots of Joker dialogue, lot more of Harvey Dent and a possible prelim glimpse at Dent's transformation into Two Face, though we do not see Two Face in the trailer. Dent does have one awesome line in the trailer; he says, “You either die a hero or you live long enough to become the villain.”
