Just popping in to say...
NO JESSICA SIMPSON!! I don't care if she has boobs!

Ugh, I'm gonna have nightmares about Jessica Simpson being in a Nolan Batman film, OMG, thanks a lot guys.
Regarding the timing of the Harvey Dent scarring...I suppose it would depend on how the trilogy will end. Will Two-Face be captured, or would he be free a la Scarecrow at the end of Begins? I personally don't think there would be enough time to scar him, chase him, and then capture him in one film. It feels too contained, and I think that would definitely shortchange the character of Two-Face.
I think it would be possible to scar Harvey at the end of TDK, after showing his good side and his mental breakdown. It would hinge on great writing and great acting, but you could do it. Like, I knew Gordon was a good cop in his first two scenes in BB. The audience didn't need an entire movie to get that, since Oldman's acting was spot-on.
I'm not really fighting for one side or another, but I really believe that they have to really foreshadow the emergence of Two-Face by the end of TDK, they way Joker was foreshadowed.

If they don't end TDK with Harvey in the hospital after being scarred, then they'd probably have to end TDK with Harvey doing something that shows his dark side and then flipping a coin. Something like that.
And I completely agree with the pics from TLH and TKJ and TMWL.
