Agreed with Jiri and KG. A way to divide the teams...as long as sterotyping doesn't carry on (ie the asian group wins because they cheesily got to use chopsticks in some event that the others doesn't

), then its much ado about nothing.
And who cares if people cheer for a certain group. Coming from a sports board where people viemently hate and treat like 2nd class citizens, players, teams, and those teams fans based on that they wear Beluga whale's on their jersey, or blue and orange (oops sorry SCH, "Oiler copper") trimmed jerseys....
And agree with fotze. I am sure there will be a couple of contestants who will be outspoken and subsequently villified and punted out at even a hint of intolerance.....a whole bunch of tears as the great divisions in Amercain culture will all be brought together in a harrowing event, and any issues will be smoothed over with them all singing kumbya at the end.
All this while members of the "ethnic" tribes probably turn out to be more "white" then most within the "white" team.
And my idea for Survivor fot he past 6 years has been to have it in the NWT come summer solstice...so there is little chance for sleep with almost 24h of day light.
