I think we have more evidence that Amanda does make the finals then we do that she doesn't.

1. When asked who he wanted to win Ozzy said he didn't want to jinx anyone. This was after the show was finished filming. The only ones he wouldn't want to jinx are Amanda and James and since James is out it has to be Amanda.
2. Ozzy is bursting with adoring emotions. If that is during the last tribal counsel I can't really see him talking to Amanda if she is on the jury next to him.
The only thing we have that makes it look like Amanda won't make it is Eric's interview. Also I don't see anyway that Parv doesn't make it to the finals. All of them would take her since she has made many on the jury mad. Plus they are all close to Parv. I don't really care who wins but I don't really want Nat to win. All four have played a good game though.
