I don't think Locke is dead neither. Did you see Jacob sitting on the chair? I read about the 5 deaths quite a while ago. There are 2 episodes left, with the second being the 2 hour finale. I predict there'll be either 2 survivor deaths (Charlie, Sayid or Kate?) and 1 others death, or 2 major Others deaths (Ben, Juliet, Mikhail, Richard or Tom) and 1 survivor death plus 2 minor others/survivors that don't have much screentime. Maybe Penny too...
