Well we now know 5 of the Oceanic 6....Kate, Hurley, Jack, Saeed and Ben.
I find it extremely interesting that Saeed is working for Ben. Could it be that he's taking out the people that were tryng to get to them at the island?
Seeing as though it seems the Oceanic 6 are the only 6 to get off, I really want to know why!!!
Also, the part where the woman counts down the arrival of the package. It seems the package is traveling at or above the speed of sound, but theres a 30min delay (as we see on the timers) between its actually landing...I'm thinking, TIME DILATION. The only real possibility for this I think would be that they're in another universe, or they're somewhere where a wormhole needs to get them there. I know its VERY fatfetched, but its an idea that time dilation supports I suppose...
Also, the timid technowiz guy from the boat was very firm in making sure the chopper pilot took exactly the same bearings out that he did going in.
