There's going to be Tiers as you move up and through the ranks which will unlock new Islands and new modes.
Tier 1 - (Starting Tier) - Basically 16 people, 1 idol per tribe with no respawn and no twist.
Tier 2 & 3 - (Getting there) - Basically more twist like tribe swaps - idol respawns will come into play and legacy advantages. 18 to 20 cast
Tier 4 - (Idol Mania) - The way Erik describes it is there's a bunch of twist and advantages that you can use in the game and super idols that can save 2 people at tribal, nixing two vote super advantages. Basically crazy and twist nonstop all season long. 24 person cast
