To be completely honest, I don't really care.
The two skins revealed so far look pretty awesome. I would definitely rock a pirate Kano if I ever played him or a kold war Skarlet.
Having said that, being a Canadian and liking the look of Baraka. Give me Beaver Baraka.
Or an Aunt Jemimah Raiden who throws maple syrup instead of thunder.
I'll even take Sub-Zero with a Canadian Hockey jersey on.
Being Canadian, I feel most comfortable ripping on my own stereotypes. But for America I wouldn't be surprised to see a straight up american flag skin, probably Sonya or something.
Japan it would be cool if we saw some sort of Mario related skin.
