It is going to be very difficult for someone to make another Batman film anytime soon. Comparisons will inevitably be made to Nolan's recent films and they would obviously be subject to harsh criticism from Nolan fans. From a summer blockbuster standpoint, the Nolan films will be very hard to better. A TV version of Batman however would not be in direct competition with Nolan's Batman. It would not have the same budget of the films and would show a different kind of Batman. It would be competing with the old campy Batman TV series which is hardly competition at all.
