With this news, I think it's safe to say mokap's chances are pretty slim.

None because it's just a faction gimmick? I don't think D'vorah belongs to any of those so...

I highly doubt any characters will be ruled out. I also think it's possible to see a Character such as Quan Chi fighting as a White Lotus. It's possible that your characters costumes could have variations to fit with the theme of the clan in which I think would be amazing to see. What would a noble Quan Chi or Scorpion look like? Colors in MK are a very big deal. Special Forces characters might have a Green or camo military theme, White Lotus has the White monk theme, Black dragon would be black and thuggish, Brotherhood would also be black but wicked, and the Lin Kuei would have a ninja theme but I'm not sure about the color.

I don't think every character will be a member of a clan but maybe 2 or 3 per. That would give you some diversity in the menu screens. Also look at the character reveals thus far,

White lotus- Kung Lao

Brotherhood of Shadow- Quan Chi

Black Dragon - Kano

SpeciaL Forces- Cassie Cage

Lin Kuie - sub Zero

I Don't think anyone else revealed so far is categorized.
