Actually, I'm not sure Austin will vote for him outright. He said (I think in his interview) that he's going to try to vote for the most deserving person, whether that person be on his old tribe or not. If he goes by who's winning immunity, yeah, it'd be Terry, but he might consider other factors.
I think it depends on how much of a "grudge" the eliminated Casaya members have. Courtney and Shane might not vote for any of the remaining three if they feel really betrayed. But from Shane's exit interview, it sounded like he didn't really hold a grudge. Bruce is a wild-card since he wasn't voted out.
I think everyone has a good chance right now.
