Okay, I think you should move Charlotte up on your death list. I'd put her right below Claire (who I think is already a goner. Wondering out into the woods, at night, by yourself? Not a good decision with polar bears and smoke monsters about) in terms of people who are going to eat it.
a) Someone from the freighter team is bound to die because let's face it, if you recently came to the island and it wasn't by way of Oceanic 815, your odds of survival are significantly lowered. Only Bernard is still alive from the tail section and there were like 25 of those guys. I suppose a few of them got drawn into the Others clan, but even they're not doing so well as of late. Alex, Mr. Friendly, Carl, Ethan, Goodwin, and some more randoms have all met with an untimely end; the island's not exactly helping its chosen people out these days.
b) I think Frank gets a free pass to basically go and disappear in the real world. Freighters on the island have a higher chance of dying because, unless you're Sayid, the island is a lot more dangerous. Plus, Frank's a fairly likable guy and he's pretty useless to everyone now that the island has moved somewhere (or somewhen).
c) Miles should be pretty safe because of the whole talking to dead people. We're gonna need someone to talk to Jacob/Christian Shepherd and Claire. Now that Locke is obviously off the island, I think Miles makes a pretty good candidate for that. He also has some snappy one liners; who doesn't like a good, snappy one liner?
d) As mentioned below, Faraday's probably the safest of the Freighters as the resident time travel expert.
e) So that leaves Charlotte. She's a bitch, she's always frowning, and no one likes her anyway. What is she again? An anthropologist? Archaeologist? She's basically useless. We know her big reveal is that she was born on the island (or so Miles would lead us to believe), but where does that really get her? And is that even true? Plus, she has the potential to fulfill the heart string/sacrifice death due to Faraday's (currently) unrequited love for her. So unless the island steps in to save one of its own, I doubt she'll live to see the end of the season.
On a related, but somewhat different note, I am totally ready for the Sawyer/Juliet hookup. If I have to resign myself to some Jack and Kate love, then they might as well free Sawyer up for someone awesome and badass (a.k.a. Juliet. I like her so much more than Kate).
