Who will actually win:
Based on odds you would think that a white or latino would the best chance since they are essentially the same race, just different ethnic groups. That gives them 10 chances to win, while the blacks and Asian only have 5 each.
Since people tend to associate with people who are similar to them that gives the white and latino contestants more people to make alliances, and the game is all about who you are allied with.
Asians would seem to have the next best chance, since they tend to get along better with whites and latinos than blacks do.
Blacks would seem to have the worst chanc again, because of the 4 ethnic groups, blacks are the most 'different' and therefore in theory would have the hardest time making alliances.
Of course all this is based soley on race and goes completely out the window when dealing with individuals.
The show should be won by either someone who is a charismatic group leader (Richard season 1 Ethan season 3) or someone who hangs on with the right alliance and wins at the end because they are more liked (Tina season 2) of course we can't forget the "hot babe" as well (Jenna season 6 or Amber All-Stars)
