'Harper's Island': Who's gonna die next?

Harper's has a trashy-ish I Know What You Did Last Summer vibe -- but I found it to be quite a nice little trifle last week. Let's just say it's one of my new guilty pleasures.   Basically, the show is about a wedding party who goes to an island off the shore of Seattle for the nuptials and, as the creepy-voiced little girl Madison keeps saying when the show cuts to commercials, most of the folks are going to be killed off "one by one." 

Do you have any early theories, PopWatchers? Who's killing? Who's dying next? Are you even watching?
