Well it's not really speculation it's pretty obvious. If you go on the arkhamhasmoved website, you can see someone who is portraying uncle sam in a build board. Except in one hand he's holding a gun. Well if you look at that hand, you can obviously see that it is different from the other hand. It can only be one person, two-face. Also backing this up is at the end of Batman AA, you are talking to gordan and on his radio you hear that Harvey Dent (AKA Two-FAce) is robbing a bank and that he was escaping. Nothing really special. Pretty obvious. But also another thing about the ending. The last scene of the game is either scarcrow, or bane is seen coming up from from the water and grabbing a crate of Titan. What do you guys make about that?
