2. Joseph Gordon Levitt's Nightwing Is Too Good To Pass Up
This is practically the elephant in the room when it comes to anything involving Batman, in the wake of The Dark Knight Rises. Conventional wisdom would say that you dont just play a card like Joseph Gordon-Levitt at the end of the game, not unless you intend to keep the game going. His performance in the final installment was so adept to Nolans sensibilities within the universe, itd be a huge shame to simply see the character of Robin John Blake simply disappear into the realm of What If? At the same time, its pretty much ridiculous to bring Batman back into the fold: he "died" saving Gotham, making himself a symbol to all who needed hope. He made the city finally believe that he was there to do good all along, and in the process he did the greatest deed the city had ever seen. Needless to say, it would completely undermine that ending (and Alfreds tears) to bring back Batman as if he never left - while Batman is a symbol, a symbol is what he should remain. Mr. Nolan pretty much guaranteed this with killing Batman, allowing Bruce Wayne his happy ending, and setting up Robin as the new successor. So, Nightwing is the best course of action to take if theres any hope to preserve this continuity properly. While Mr. Gordon-Levitt is somewhat skeptical himself about whether the series "needs" to continue, who's to say that he wouldn't be persuaded with the right angle on the material? Which leaves the door open to a change in management, and one prospective director chooses himself...
