It was asked before Marvel was released if there was a possibility of a DC crossover and the game director simply said that they were focusing on Marvel at the moment. Do you think there should be just a LEGO Superheroes videogame?
I think it's far less likely to happen under current management that it would have been 10 years ago. But the movies are huuuuuge business now and run the respective properties and there's no way that Disney or Warner Bros will do anything that might serve to promote the other's film franchises.
