Okay, I've seen this discussed in the episode thread a lot, and there are general "twist" topics, but I was suprised to find neither a specific topic on Palau, or the revelation that it will be packed up somehow with 20 of these famewh@res!
The major theories to explain the 20 people seem to be:
1.) perhaps an EVEN LONGER season
2.) two tribes, some double eliminations (or some immediate boots the moment they step on the island)
3.) odd small tribes, four tribes of four or five tribes of four, and SOMEHOW some control to make this workible since they had enough trouble with 3 tribes
4.) no tribes (or one, I suppose) at least to start--where the show starts off more Darwinian with every man or woman for his or herself and people clump together for other reasons. Obviously you could have a LOT of variations on this.
a.) people compete in teams (which may or may not be arbitrary) for immunity, but vote individually for eviction
b.) people both compete and vote individually--although naturally alliances come into play
c.) people compete and vote in teams/tribes, but they are arbitrary each week
d.) some combination of the above. Individual competitions and informal alliances for several weeks, and then later imposed formal tribes springing from some system based on popularity for the leaders and then those leaders picking tribe members.
As long as we are being specific to Palau, I suppose there's also a heck of a lot to wonder about concerning the old Navy wrecks an other war wreckage around the island. Will the show make some lame Pearl Islands attempts to tie it in to gameplay, or is it just scenery?
