The Island is Waiting

Okay, so I'm finally caught up with LOST and I'll be ready for the season premiere next week. Do I understand everything? Not in the least, but now I know how the Oceanic 6 evolved.

Is Locke really dead? Did the island really move? What happened to the people on the freighter when it exploded? Are the rest of the survivors still alive? What about the Others? Will the Oceanic 6 return to the island?

Eagerly awaiting Season 5 ...
