SPECULATION Star Wars Battlefront Heroes

Hey everybody! With the release of the Battlefront Beta we are getting everyone's reaction to the new game. This week we also found out some new details about game modes and other playable heroes (thanks to some industrious hackers):

So now we have six total : Darth Vader, Boba Fett, Luke, The Emperor, Han, Leia

After playing the beta I assume many of you are heartened that there will be some dedicated hero vs villain modes, making the ability to play as your favorite characters far easier than getting a power up in the massive multiplayer modes. As much fun as I found these characters in the game, it seems like a lot fewer characters than previous SWBF games.

With all this in mind- do you think Dice will add more to the DLC?
If so- which heroes/villains should be added?

My first thoughts (keeping strictly OT as the game has so far) are Obi-Wan or Chewbacca, and maybe an Imperial Officer and another Bounty Hunter for the Imperials.
