In my opinion the new film shouldn't try hard to either emulate or be different from the Nolan trilogy, but just be as good a Batman film as it can be and let any similarities or differences happen naturally.
Case in point, Begins. It had a some things in common with the 89 movie - a black, rubbery suit, a car chase, a smoky,cramped noir look. But in most ways it was completely different - story that made sense, focused more on Batman, explained his origin and weapons, felt like a modern thriller. And by TDK the 89 feel was gone.
I would like the new series to move into its own naturally, the same way Begins moved us from Burton to Nolan naturally, being itself without throwing out the good just to be different.
