Warner Montreal hinted during the latest anniversary of Batman something related with the Dark Knight. The game has been rumored several times through different forms. The new Batman iteration could be called:

Batman: Arkham Legacy

Sabi, a person that leaked ton of info from E3, has made that commentary on Twitter. He was legit about former leaks, this time would not be different.
