Ozzy is just so boring. He'll dominate challenges, make the merge, get booted the moment he is not immune. He's a coattail ride for the majority alliance and always the first one to cut loose from it. Predictable humbug. Also he's plain dislikeable aside from his debut season in the Cook Islands.
Cirie and Sandra should be fun together. If they are on the same tribe (honestly shouldn't be for balance but I digress), I can see them becoming the masters of the game.
Saw the rest of the list and it seems ok. I like seeing Freberg again and Tony should be interesting just to see how he adapts as his original gameplay would be hard to replicate with everyone knowing what he does. Could see Sarah booting him off early due to bitterness, sadly.
edit: oh wait nevermind, there's Culpepper and Troyzan. Both suck.
