The highly anticipated 'Batman: Arkham City' video game trailer has hit (check it out after the jump), which just might prove to be a hint for Christopher Nolan's final forays into the city -- or a nice bit of gossip to keep us guessing in anticipatory glee.

For over a year now, we've been wondering what Nolan would do for his third and final Batman installment, now titled 'The Dark Knight Rises.' The rumor mill has been jumping with speculation that spans much of the comic hero's history. We know there won't be the Joker -- Nolan's leaving that character to the late Heath Ledger, and Harvey Dent won't be returning. To fill the spaces left by the last villains, we've heard murmurs that Joseph Gordon-Levitt was gearing up for The Riddler, Charlize Theron and Vera Farmiga were rumored to be love interests, and reports claimed the slimy Killer Croc would be the new Big Bad.

But the one thing we do know is leading to a new possibility. In October came the inspiring news that Tom Hardy was reuniting with the director to enter the Batfold, and though most readers want to see him as the Riddler, Nolan has stated that the main villain in 'Dark Knight Rises' "won't be the Riddler."

Perhaps the Croc rumors are right, but could the highly charismatic Hardy take a cue from Peter Sarsgaard's misshapen Hammond ('Green Lantern') and play the villainous Hugo Strange instead?
