You know that Batman: Arkham Knight TV spot you have been seeing for a bit. Well it is just part of bigger trailer. The trailer sets the town as it sounds like Gordon is giving Batman eulogy. This may go with the rumor of Batman end in the game but remember that you can change that as all of the missions including the side missions then you can change the bats fate. For now just sit back and enjoy the Batman voice.
