Here's some very interesting spoilers from another site:
Part One:
"First off, let me say that I am an insider. No, I won't tell you where I received this information or what role I play in terms of LOST production, if any, so don't bother to ask - I won't answer.
Okay, now that that's out of the way, here is what I can tell you which you'll learn about very soon.
1. In Exodus part II and III we're going back to the airport, and this time we'll be introduced to the tail section cast (Glenn Cannon, John Walcutt, Michelle Rodriquez) who'll be permanent castmembers next season. They'll be 3 of 4 survivors from the tail-end of the plane who landed on the other side of the island.
2. We'll find out in Exodus II that Rose's husband did survive the crash but went missing a few days after the crash when he went off into the jungle looking for Rose (no actor will be cast for this role until next season).
3. The new castaways will be introduced after the visit from Danielle and her dire warning to run, hide or die.
4. The circle of the mysetrious island is to replace what's been lost or needed. This goes with fresh water, livestock, and humans. The key is that everything has a balance.
5. Through a series of flashbacks we'll see how and why the plane went down. This is where you'll see a small percentage of the monster (who is responsible for the plane ripping apart). "
Part Two:
"I wouldn't attempt to give everything up. Why ruin the biggest surprise that will definitely be talked about around the watercooler for months. I only give what is needed to know at this point.
I can, however, delve into a little bit more detail without blowing my cover.
1. Look for the man with the Hawaiian shirt in Exodus II.
2. A male at this time won't be returning, and another will only return next season for only 2 early episodes. Clue: One isn't as popular as the other with the ladies.
3. Those mysterious voices in the jungle have faces, but not all of them will be seen this season. They do have running feet, and one in particular will be very familiar.
4. Hurley is called upon to open something up where tools couldn't.
5. The view of the island is "breath-taking"
