This really wouldn't ruin too much, but just in case you want to be 100% totally surprised about everything, don't continue reading to see the Lost Spoilers.

The cast of Lost is just as in the dark about the show as we are.  So they sat down with the producers, asked some questions and got some pretty vague answers...
Jorge Garcia (Hurley): "Is Ben in the coffin?"
Carlton Cuse: Come on, Jorge!
Damon Lindelof: Seriously! [To Cuse] He's just trying to make sure it's not him. It's process of elimination. The next question is, "Is it Michael?" [Laughs]
Cuse: Before the end of the year, you will know who's in the coffin.
Lindelof: And Jorge will definitely know before anyone else.
Yunjin Kim (Sun): "Is Aaron actually one of the Oceanic 6?"
Cuse: We're not officially saying yet. We want the audience to engage in an active debate about who the Oceanic 6 are.
Lindelof: Following [Sayid's] episode, we got several inquiries we weren't anticipating about, 'Is Ben a member of the Oceanic 6?' He could've assumed the identity of somebody on the plane [with] no surviving family members. Who the actual six are is very much in play through the end of the [March 13th] episode. We'll confirm or deny after that.
Josh Holloway (Sawyer): "Is it Jack's turn with Kate?"
Cuse: [Laughs] That doesn't sound very romantic, but I guess we get the underlying meaning. The Jack-Kate situation remains unresolved and probably will be for a while.
Lindelof: We will say we haven't seen the last of Sawyer and Kate this season. Not by a long shot.
Evangeline Lilly (Kate): "Did Michael reach the mainland? Go home? Come back to rescue us?"
Cuse: The good news is that Evie will get all of her answers in [the March 20th] episode.
Lindelof: Well, most of them.
Cuse: Those questions form the basis for that episode. Evie should be somewhat happy.
 AHHHH!  SO many questions!!!  Sounds like we will get a lot of our answers soon :)  Is anyone else dying to find out what happens?!?  Read the rest of the Q&A's with the cast members and directors here.
