Ok... the title warned you!

TVGuide channel had a preview... which I didn't watch until after the 1st episode (grin... forgot I had it on Tivo and watched the 1st episode real time)

There is NO Exile Island this year, but there are TWO Hidden Immunity Idols... one in/near each camp

The twist is that each camp's HII is for the OTHER tribe, and only the members of the OTHER tribe will be give clues to where to find the HII in the opposite camp

Exactly how that will be done was not said
