Maybe bring back  the Dutch with Willem van Oranje. I'd love to play a heavily mercantile seafaring civ. They'd probably make it like playing England with a higher focus on commerce than war.

Stalin. Churchill. Others.

Christ. I am german, but I can not understand your obsession with Hitler. Well, all of the leader have a progressive & positive tone - as does the whole game. Thats why Hitler is not in there, as well as Stalin or Genghis Khan. Also it would get banned in Germany, since it is alternate history. I am not sure, but I think in correct historical representation you can put Nazis in Games now. At least as opponents. But that changes over the years (see CoD vs. Return to Castle Wolfenstein, though the latter is far from historical correct). 
 
This game is about progress, and not sadistic nationalist bullshit. Pick a civ. You will find a era of unspoken cruelty and genocide in it. No place for that in Civ IMNSHO!
 
Personally I would think that Kemal Atatürk would be great for the Ottomans. 
 
But I doubt they will introduce more leaders only. But more Civs. I want the Vikings, the Dutch and heck maybe even the Austrians!

 there are several WW2 RTS games featuring the wehrmacht as a playable faction, of course in none of them you're taking the position of hitler himself and doing genocide and stuff but, yeah   

GRIGORI RASPUTIN!!! 
 
Also, Churchill, Charlemagne, Mao, Qin Shihuangdi, Trotsky (honestly, I don't get how people prefer Lenin to this guy), Attila the Hun (Possible Barbarian City-State, able to draw barbarian camps into it's empire if not destroyed quickly enough), Vladimir the Impaler, Kaiser Wilhelm I, Edward Teach, Theodore Roosevelt, Richard the Lionhearted, Shaka Zulu, and  Nikita Krushchev. 
 
I think multiple leaders should be allowed for each civilization, so I can simulate an American Civil War between Teddy Roosevelt and Ronald Reagan.

"  I ain't trollin' but why has no civ game had Hitler in it, I mean its hardly "too soon" or am I being insensitive, IDK, but I'd like to see someone Reppin' ye olde Scotland, yeh sure you've got Britain but come on, when they say Britain in that game they mean England. Perhaps William Wallace, or Boadicea like in Civ IV     "

the game would get so totally banned in germany.   i really prefer bismarck as a german leader. "

Watch out fox news will google hitler, come to this thread, and make a news report stating that every  Civ player is a nazi. and "want adolf hitler".

Obama

I think if Hitler was in the game, they couldn't sell it in Germany. 
 
Germany has very strict laws about Nazi remembrance, even in fiction, and usually if it's not straight history, they don't allow it. 

I'm not sure you can have Mandela while he's still alive? And no love for Kitchener?
